Purpose. Create a new source material of soybeans without pubescence, determine its selection value for the efficient use of processed products in animal nutrition, which will ensure high productivity of the latter. Quantitative and qualitative indicators of seeds are important economic and valuable features. The lack of pubescence on plants is unique.Methods. Field, special, laboratory and mathematical-statistical.Results. The minimum fat content of 20.88% was observed in the seeds of the non-pubescent variety ‘Kobra’, 23.73% in the line No 305, and 25.02% in the line No 22. The varieties ‘Diamant’ and ‘Antratsyt’ had a high fat content – 24.08–25.83%. The protein content in the green mass of promising lines was very low – up to 16%. The fat content was in the range of 2.1–5.3% with the maximum value in the lines No 3 and No 7 – 4.67–5.26%. The protein content in ‘Anakonda’ seeds and No 1 and No 9 lines was 36–37%, in standard varieties – at the level of 29.5–35.63%. A comparison of new non-pubescent lines with standard varieties and the most productive varieties ‘Diamant’ and ‘Adamos’, which are included in the Register of Plant Varieties of Ukraine and meet the requirements for efficient use in fodder production.Conclusions. Lack of pubescence in soybean plants is an extremely rare and atypical phenomenon. There are no such varieties in the state register of plant varieties of Ukraine. More than 50 non-pubescent lines exceed the indicators of economic suitability of national standards and modern varieties. Lines No 4, No 5, No 7, No 8, which had more than 15% protein in the green mass, should be involved in the selection process to create fodder varieties. The ‘Anakonda’ line has a nutritional value with a minimum content of linolenic acid in the oil (6.08%). Increased oleic acid content was observed in varieties ‘Adamos’ (35.01%), ‘Diamant’ (33.53%), ‘Ametyst’ (31.39%). | Мета.

Purpose. To determine the content of biochemical compounds in fruits of M. domestica Borkh. varietal samples, select the most promising ones for use in further breeding, and recommend for use in various directions, given the biochemical complex of signs, taste and marketability of the fruit. Methods. We used generally accepted methods for determining the biochemical composition of fruits (soluble so­lids (SSR) according to GOST (State Standard System) 29030-91, total sugars according to GOST 8756-13.87; polyphenol composition according to the method of L. I. Vigorov (1968), vitamin C according to the method of A I. Ermakov (1972); tit­rated acids – according to GOST 25555.0-82). Results. Nine cultivars of apple trees were analyzed for the biochemical composition of fruits, namely the apple tree cultivar ‘Vydubytska Plakucha’ (‘V. p.’) and various hybrids created on its basis from the collection of the fruit plant acclimatization department of the M. M. Hryshko National Botanical Gardens of National Academy of Sciences of Ukraine. Selected forms are sources of 1–5 important biochemical characteristics (solids content, glucose, sugars, ascorbic acid, titratable acid) and promising for use in breeding. According to the dry matter content – the lowest rate was found in hybrid ‘V. p.’ × ‘Renet Symyrenko’ (16.68%), the highest in the hybrid – ‘V. p.’ × ‘Renet Oranzhevyi Coksa’ (22.87%), rates of ascorbic acid content varied within (6.0–12.25 mg%), total sugars (10.37–18.23), acids (0.74–1,67 respectively). The most interesting for introduction and breeding are hybrids with a high content of biochemical parameters, namely: ‘V. p.’ × ‘Renet Oranzhevyi Coksa’, ‘V. p.’ × ‘Golden Delicious’ and ‘V. p.’ × ‘Parmen Zymovyi Zolotyi’. Conclusions. The content of the biochemical composition of the fruits, taste and marketability were characterized, and varietal samples of hybrids of the apple tree ‘Vydubytska Plakucha’ were distributed in the directions of use in order to improve the quality of life of the population. According to the biochemical indicators of the cluster analysis of the studied apple hybrids, close relationships were found between the three groups necessary in the future for breeding when selecting parental forms for an improved biochemical composition of the fruit (including hybrids ‘V. p.’ × ‘Renet Oranzhevyi Coksa’, ‘V. p.’ × ‘Golden Delicious’ and ‘V. p.’ × ‘Parmen Zymovyi Zolotyi’, titrated acid hybrids ‘V. p.’ × ‘Starkrimson’, ‘V. p.’ × ‘Parmen Zymovyi Zolotyi’ and ‘V. p.’ × ‘Renet Symyrenko’, tannins hybrids ‘V. p.’ × ‘Slava Peremozhtsiam’ and ‘V. p.’ × ‘Starkrimson’); and to expand the assortment of apple trees according to the planned commercial signs. Hybrids of the apple-tree cultivar ‘Vydubytska Plakucha’, created in the NBG using old and valuable modern apple-tree cultivars, indicate the promise of producing high-yielding, large-fruited varieties with a high content of biologically active substances

Созданные в НБС гибриды сорта яблони ‘Видубицька плакуча’ с использованием старых и ценных современных сортов яблони свидетельствуют о перспективности получения высокоурожайных, крупноплодных сортов с высоким содержанием биологически активных веществ.

Purpose. To determine the content of biochemical compounds in fruits of M. domestica Borkh. varietal samples, select the most promising ones for use in further breeding, and recommend for use in various directions, given the biochemical complex of signs, taste and marketability of the fruit. Methods. We used generally accepted methods for determining the biochemical composition of fruits (soluble so­lids (SSR) according to GOST (State Standard System) 29030-91, total sugars according to GOST 8756-13.87; polyphenol composition according to the method of L. I. Vigorov (1968), vitamin C according to the method of A I. Ermakov (1972); tit­rated acids – according to GOST 25555.0-82). Results. Nine cultivars of apple trees were analyzed for the biochemical composition of fruits, namely the apple tree cultivar ‘Vydubytska Plakucha’ (‘V. p.’) and various hybrids created on its basis from the collection of the fruit plant acclimatization department of the M. M. Hryshko National Botanical Gardens of National Academy of Sciences of Ukraine. Selected forms are sources of 1–5 important biochemical characteristics (solids content, glucose, sugars, ascorbic acid, titratable acid) and promising for use in breeding. According to the dry matter content – the lowest rate was found in hybrid ‘V. p.’ × ‘Renet Symyrenko’ (16.68%), the highest in the hybrid – ‘V. p.’ × ‘Renet Oranzhevyi Coksa’ (22.87%), rates of ascorbic acid content varied within (6.0–12.25 mg%), total sugars (10.37–18.23), acids (0.74–1,67 respectively). The most interesting for introduction and breeding are hybrids with a high content of biochemical parameters, namely: ‘V. p.’ × ‘Renet Oranzhevyi Coksa’, ‘V. p.’ × ‘Golden Delicious’ and ‘V. p.’ × ‘Parmen Zymovyi Zolotyi’. Conclusions. The content of the biochemical composition of the fruits, taste and marketability were characterized, and varietal samples of hybrids of the apple tree ‘Vydubytska Plakucha’ were distributed in the directions of use in order to improve the quality of life of the population. According to the biochemical indicators of the cluster analysis of the studied apple hybrids, close relationships were found between the three groups necessary in the future for breeding when selecting parental forms for an improved biochemical composition of the fruit (including hybrids ‘V. p.’ × ‘Renet Oranzhevyi Coksa’, ‘V. p.’ × ‘Golden Delicious’ and ‘V. p.’ × ‘Parmen Zymovyi Zolotyi’, titrated acid hybrids ‘V. p.’ × ‘Starkrimson’, ‘V. p.’ × ‘Parmen Zymovyi Zolotyi’ and ‘V. p.’ × ‘Renet Symyrenko’, tannins hybrids ‘V. p.’ × ‘Slava Peremozhtsiam’ and ‘V. p.’ × ‘Starkrimson’); and to expand the assortment of apple trees according to the planned commercial signs. Hybrids of the apple-tree cultivar ‘Vydubytska Plakucha’, created in the NBG using old and valuable modern apple-tree cultivars, indicate the promise of producing high-yielding, large-fruited varieties with a high content of biologically active substances

Purpose. To study the protein content and other economically valuable traits in soybean varieties of various origin, to determine the stability and plasticity indicators of these traits, as well as to identify varieties that are promising for use in breeding programs. Methods. Field, laboratory, biochemical and statistical. Results. In total 22 soybean varieties of various origin in terms of yield, protein and oil content in seeds were investigated. High-yield and high-plasticity varieties are distinguished: ‘Muza’, ‘Mentor’, ‘Asuka’, ‘Valas’, ‘Kofu’, ‘Asuka’, ‘Cardif’, ‘Alligator’, ‘Vyshyvanka’, ‘Suziria’ and varieties of domestic breeding with stable yield ‘Siverka’, ‘Vilshanka’, ‘Ustia’, and also the ‘Lisbon’ variety. High protein content was noted in the variety ‘Opus’ – 45.0% in 2017. This variety on average for three years showed 43.63% of the protein in the seeds, and was second after the ‘Ustia’ variety (44.3%). The highest value of the regression coefficient b = 4.289 was observed in the ‘Lisbon’ varie­ty, which shows its high sensitivity to growing conditions with a fairly low average seed protein content of 38.60%, as well as the variety ‘Silesia’ b = 4.289 with an average protein value of 42,73%. Standard variety ‘Muza’ with a low protein content of 38.60% was quite stable in the expression of this characteristic – S2 = 0.222. A number of high-oil varieties were distinguished: ‘Valas’ – 22.77%, ‘Sigalia’ – 22.7%, ‘Alligator’, ‘Siverka’ – 22.53%, ‘Kofu’ – 22.13%, standard variety ‘Muza’ – 21.77%. Conclusions. In breeding programs aimed at increasing the protein content in seeds, the following varieties should be used: ‘Opus’ – as a carrier of the maximum value of the trait, as well as ‘Ustia’, ‘Asuka’, ‘Silesia’ and ‘Kasidi’ as combining high yield and high protein content. The weather conditions of the year in different ways influenced on the manifestation of the studied traits: in a favorable year for obtaining high yields, the protein content in the seeds decreased, the high protein content accumulated in a drier year, and the oil content in seeds changed insignificantly.

Вивчити сорти сої різного походження за вмістом білка та іншими господарськими ознаками, визначити показники стабільності та пластичності цих ознак, а також виділити сорти, перспективні для використання у селекційних програмах.Методи. Польові, лабораторні, біохімічні та статистичні.Результати. Досліджено 22 сорти сої за врожайністю, вмістом білка та олії в насінні. Виділено пластичні сорти, що мають високу врожайність: ‘Муза’, ‘Ментор’, ‘Асука’, ‘Валас’, ‘Кофу’, ‘Кардіф’, ‘Алігатор’, ‘Вишиванка’, ‘Сузір’я’ та стабільні за врожайністю сорти вітчизняної селекції ‘Сіверка’, ‘Вільшанка’, ‘Устя’, а також сорт ‘Лісабон’. Найвищий уміст білка відмічено у сорту ‘Опус’ – 45,0% у 2017 році. Цей сорт у середньому за три роки показав 43,63% білка в насінні і поступався тільки сорту ‘Устя’ (44,3%). Проте значно вище значення коефіцієнта регресії b = 4,289  у сорту ‘Лісабон’ показало його високу чутливість до умов вирощування при досить низькому середньому значенні вмісту білка в насінні (38,60%), як і сорт ‘Сілесія‘ (b = 4,289) при середньому значенні білковості – 42,73%.  Сорт-стандарт ‘Муза’ при низькій білковості 38,60% був досить стабільним за проявом цієї ознаки – S2 = 0,222.  Виділено низку сортів з високим вмістом олії в насінні: ‘Валас’ – 22,77%, ‘Сігалія’ – 22,7%, ‘Алігатор’,  ‘Сіверка’ – 22,53%, ‘Кофу’ – 22,13%, сорт-стандарт ‘Муза’ – 21,77%.Висновки. У селекційних програмах, спрямованих на підвищення вмісту білка в насінні, слід використовувати  сорти: ‘Опус’ – як носій максимального значення ознаки, ‘Устя’, ‘Асука’, ‘Сілесія’ та ‘Касіді’ – як високоврожайні з високим умістом білка. Погодні умови року неоднаково впливали на прояв  досліджуваних ознак: у сприятливий для отримання високих урожаїв рік вміст білка в насінні знижувався, у посушливіший рік уміст білка був вищим, а вміст олії в насінні змінювався незначно. | Цель.

Полевые, лабораторные, биохимические и статистические.Результаты. Исследовано 22 сорта сои различного происхождения по урожайности, содержанию белка и масла в семенах. Выделено высокоурожайные высокопластичные сорта: ‘Муза’, ‘Ментор’, ‘Асука’, ‘Валас’, ‘Кофу’, ‘Кардиф’, ‘Аллигатор’, ‘Вышиванка’, ‘Сузирья’ и стабильные по урожайности сорта отечественной селекции ‘Сиверка’, ‘Вильшанка’, ‘Устя’, а также сорт ‘Лиссабон’. Высокое содержание белка отмечено у сорта ‘Опус’ – 45,0% в 2017 году. Этот сорт в среднем за три года показал 43,63% белка в семенах и уступал только сорту ‘Устя’ (44,3%). Однако высокое значение коэффициента регрессии b = 4,289 у сорта ‘Лиссабон’ показало его высокую чувствительность к условиям выращивания при достаточно низком среднем значении содержания белка в семенах (38,60%), как и сорт ‘Силесия’ (b = 4,289) при среднем значении белковости – 42,73%. Сорт-стандарт ‘Муза’ при низкой белковости 38,60% был достаточно стабильным по проявлению этого признака – S2 = 0,222. Выделен ряд высокомасличных сортов: ‘Валас’ – 22,77%, ‘Сигалия’ – 22,7%, ‘Аллигатор’, ‘Сиверка’ – 22,53%, ‘Кофу’ – 22,13%, сорт-стандарт ‘Муза’ – 21,77%.Выводы. В селекционных программах, направленных на повышение содержания белка в семенах, следует использовать сорта: ‘Опус’ – как носитель максимального значения признака, а также ‘Устя’, ‘Асука’, ‘Силесия’ и ‘Касиди’ – как объединяющие высокую урожайность и высокое содержание белка. Погодные условия года по-разному влияли на проявление изучаемых признаков: в благоприятном для получения высоких урожаев году содержание белка в семенах снижалось, высокое содержание белка было в более засушливом году, а содержание масла в семенах менялось в незначительной степени | Purpose.

Purpose of this study was to develop the main components of a model of an adaptive information system for predicting crop productivity. Methods. To conduct research on the establishment of the basic structural elements of an adaptive information model for predicting the productivity of basic crops used the method of constructing dynamic models. Results. A detailed analysis of conceptual approaches to the construction of mathematical agricultural models is carried out and the main advantages and disadvantages of modern analogues are established. It is determined that the adaptive information model is based solely on the needs of the plant and actually on the need to provide these needs with available resources in order to obtain consistently high yields with high quality indicators. The hardware and software complex must have a feedback relationship between its basic structural elements, because it significantly improves the accuracy of predicting plant productivity. Data based on the operation of certain mechanisms or indicators of weather conditions and their forecasts are used for decision making, however, if they are substantially changed, decisions about individual technology elements are reviewed. The software should be related to the economic part and should take into account market conditions and forecast data when making recommendations. In the case of low purchase prices for products, we recommend that certain agrotechnical operations (say vegetation feeding) be applied or not, in the case of significant change in growing conditions - when the application of these agro-measures will be ineffective due to the negative effects of drought, etc. Conclusions. Adaptive information system for forecasting productivity in the technological process of growing crops is formed on the basis of a model consisting of three modules of characteristics – the resultant and two components. At each subsequent stage of implementation of the model, the resulting feature becomes component, with the maximum contribution to the resulting feature of the next module.

Целью данного исследования была разработка основных компонентов модели адаптивной информационной системы прогнозирования продуктивности сельскохозяйственных культур. Методы. Для проведения исследований по установлению основных структурных элементов адаптивной информационной модели прогнозирования продуктивности основных сельскохозяйственных культур использовали метод построения динамических моделей. Результаты. Проведен детальный анализ концептуальных подходов к построению математических сельскохозяйственных моделей и установлены основные преимущества и недостатки современных аналогов. Определено, что адаптивная информационная модель базируется исключительно на потребностях растения и собственно необходимость обеспечить эти потребности доступными ресурсами с целью получения стабильно высокой урожайности с хорошими показателями качества.

Программный продукт должен быть связан с экономической частью и при создании рекомендаций учитывать конъюнктуру рынка и прогнозные данные. В случае низкой закупочной цены на продукцию рекомендовать применять или не применять определенные агротехнические операции (скажем удобрение по вегетации), кроме того, корректировать их в случае существенного изменения условий выращивания – когда применение этих элементов технологии будет неэффективно за счет негативного воздействия других факторов.

Purpose. To study the economic and biological characteristics and to reveal the genetic potential of various hybrids of Chinese cabbage depending on the climatic zone of cultivation. Methods. In the experiment, hybrids of Chinese cabbage ‘Pioner F1’ (control), ‘Villi F1’, ‘Manoko F1’, ‘Orient Star F1’, ‘Vitimo F1’, ‘Sprinkin F1’, ‘Summer Highland F1’, ‘Suprin F1’, and ‘Richi F1’ were evaluated. The experiment was laid out in a randomized block design with four replications with a single plot area of 21 m2. The container seedlings (40 days old) were planted in the middle of April according to the scheme 70 cm by 25 cm. Results. Having been planted at the same time, seed germination over the studied hybrids was not simultaneous. The first sprouted seeds (4 days after seeding) belonged to hybrids ‘Villi F1’, ‘Manoko F1’, ‘Orient Star F1’, and‘Summer Highland F1’. Seeds of the other hybrids started active germination on the 5–6 days after seeding. The highest yield of the cabbage heads was obtained from hybrids ‘Villi F1’ (31.7 t/ha) and ‘Sprinkin F1’ (28.7 t/ha), which was 10.0 and 7.0 t/ha more than in the control variant. The yield of ‘Summer Highland F1’ was 24.9 t/ha and ‘Suprin F1’ 24.6 t/ha. Under the conditions of unstable soil moisture, hybrids ‘Villi F1’and ‘Sprinkin F1’ appeared the most productive and ensured yield increase of 10.0 t/ha and 7.0 t/ha, respectively, compared to the control; and crop commercial quality was high. The highest percentage of dry matter (DM) content was in ‘Summer Highland F1’ (6.2%) followed by ‘Sprinkin F1’ (5.9%), which was 1.1% and 0.8% more than in the control. There was no significant difference between the values of the total sugars content over the variants. They ranged between 1.7 and 2.1%, which was similar to the control values. The content of nitrates in the cabbage heads of the studied Chinese cabbage hybrids was within the tolerance limit and amounted to 600 mg/kg (raw mass). Conclusions. Phenological observations of plant development and their biometric indices, depending on the varietal characteristics, indicate that under the conditions of unstable soil moisture, hybrids ‘Villi F1’ and ‘Sprinkin F1’ were more yielding and ensured yield increase of 10.0 t/ha and 7.0 t/ha, respectively, compared to the control. The crop commercial quality was high. The long growing season of ‘Richi F1’ (93 days) did not affect the crop quality and yield and demonstrated the lowest productivity compared to the control and the other experiment variants.

Цель. Исследовать хозяйственно-биологические особенности и раскрыть генетический потенциал различных гибридов капусты пекинской в зависимости от климатической зоны выращивания. Методы. Вариантами опыта были гибриды капусты пекинской ‘Pioner F1’ (контроль), ‘Vili F1’, ‘Manoko F1’, ‘Orient Star F1’, ‘Vitimo F1’, ‘Sprinkin F1’, ‘Summer Highland F1’, ‘Suprin F1’, ‘Richi F1’. Площадь учетного участка 21 м2. Опыт закладывался в четырех повторениях, исследуемые варианты размещали методом рендомизированных блоков. Кассетную рассаду в возрасте 40 суток высаживали во второй декаде апреля по схеме 70 × 25 см. Результаты. В один срок посева у гибридов всходы появлялись не одновременно и первые отмечены у гибридов ‘Vili F1’, ‘Manoko F1’, ‘Orient Star F1’ и ‘Summer Highland F1’ – на 4 сутки после посева, а в остальных – массовые всходы наблюдались несколько позже, на 5–6 сутки после посева. Самый высокий товарный урожай головок получили у гибридов ‘Vili F1’ (31,7 т/га) и ‘Sprinkin F1’ (28,7 т/га), что на 10,0 и 7,0 т/га больше, чем в контроле. Существенно ниже была урожайность у гибридов ‘Summer Highland F1’ – 24,9 и ‘Suprin F1’ – 24,6 т/га. В условиях неустойчивого увлажнения более урожайными были гиб­риды ‘Vili F1’ и ‘Sprinkin F1’, которые обеспечили прирост урожая к контролю 10,0 и 7,0 т/га, а продукция имела высокое товарное качество. Самый высокий процент сухих растворимых веществ установлен в головках гибридов ‘Summer Highland F1’ (6,2%) и ‘Sprinkin F1’ (5,9%), что на 1,1 и 0,8% больше контроля. По сумме сахаров не отмечено существенной разницы между вариантами, данный показатель был на уровне контроля (1,7–2,1%). Содержание нитратов в головках исследуемых гибридов капусты пекинской было в пределах допустимой нормы 600 мг/кг сырой массы. Выводы. Фенологические наблюдения за развитием растений и их биометрические показатели в зависимости от сортовых особенностей указывают, что в условиях неустойчивого увлажнения более урожайными были гибриды ‘Vili F1’ и ‘Sprinkin F1’, которые обеспечили прирост урожая к контролю 10,0 и 7,0 т/га, а продукция была высокого товарного качества. Длительный период вегетации у гибрида ‘Richi F1’ – 93 суток не повлиял на качество и урожайность культуры и обеспечил низкие показатели относительно контрольного и исследуемых вариантов. | Мета. Дослідити господарсько-біологічні особливості та розкрити генетичний потенціал різних гібридів капусти пекінської залежно від кліматичної зони вирощування.Методи. Варіантами досліду були гібриди капусти пекінської ‘Pioner F1’ (контроль), ‘Vili F1’, ‘Manoko F1’, ‘Orient Star F1’, ‘Vitimo F1’, ‘Sprinkin F1’, ‘Summer Highland F1’, ‘Suprin F1’, ‘Richi F1’. Площа облікової ділянки 21 м2. Дослід закладався в чотирьох повтореннях, досліджувані варіанти розміщували методом рендомізованих блоків. Касетну розсаду віком 40 діб висаджували в другій декаді квітня за схемою 70 × 25 см.Результати. За одного строку сівби у гібридів сходи з’являлись неодночасно і перші відмічено у гібридів ‘Vili F1’, ‘Manoko F1’, ‘Orient Star F1’та ‘Summer Highland F1’ – на 4 добу після сівби, а у решти – масові сходи спостерігали дещо пізніше, на 5–6 добу після сівби. Найвищий товарний врожай головок одержали у гібридів ‘Vili F1’ (31,7 т/га) та ‘Sprinkin F1’ (28,7 т/га), що на 10,0 і 7,0 т/га більше, ніж у контролі. Істотно нижчою була врожайність у гібридів ‘Summer Highland F1’ – 24,9 і ‘Suprin F1’ – 24,6 т/га. В умовах нестійкого зволоження врожайнішими були гібриди ‘Vili F1’та ‘Sprinkin F1’, які забезпечили приріст урожаю до контролю 10,0 і 7,0 т/га, а продукція була високої товарної якості. Найвищий відсоток сухих розчинних речовин був у головках гібридів ‘Summer Highland F1’ (6,2%) і ‘Sprinkin F1’ (5,9%), що на 1,1 і 0,8% більше за контроль. За сумою цукрів не відмічено істотної різниці між варіантами, даний показник був на рівні контролю (1,7–2,1%). Уміст нітратів у головках досліджуваних гібридів капусти пекінської був у межах допустимої норми – 600 мг/кг сирої маси.Висновки. Фенологічні спостереження за розвитком рослин та їхні біометричні показники залежно від сортових особливостей вказують, що в умовах нестійкого зволоження врожайнішими були гібриди ‘Vili F1’та ‘Sprinkin F1’, які забезпечили приріст урожаю до контролю 10,0 і 7,0 т/га, а продукція була високої товарної якості. Тривалий період вегетації у гібриду ‘Richi F1’– 93 доби, не вплинув на якість і врожайність та забезпечив найнижчі показники відносно контрольного і досліджуваних варіантів. | Purpose. To study the economic and biological characteristics and to reveal the genetic potential of various hybrids of Chinese cabbage depending on the climatic zone of cultivation.Methods. In the experiment, hybrids of Chinese cabbage ‘Pioner F1’ (control), ‘Villi F1’, ‘Manoko F1’, ‘Orient Star F1’, ‘Vitimo F1’, ‘Sprinkin F1’, ‘Summer Highland F1’, ‘Suprin F1’, and ‘Richi F1’ were evaluated. The experiment was laid out in a randomized block design with four replications with a single plot area of 21 m2. The container seedlings (40 days old) were planted in the middle of April according to the scheme 70 cm by 25 cm.Results. Having been planted at the same time, seed germination over the studied hybrids was not simultaneous. The first sprouted seeds (4 days after seeding) belonged to hybrids ‘Villi F1’, ‘Manoko F1’, ‘Orient Star F1’, and‘Summer Highland F1’. Seeds of the other hybrids started active germination on the 5–6 days after seeding. The highest yield of the cabbage heads was obtained from hybrids ‘Villi F1’ (31.7 t/ha) and ‘Sprinkin F1’ (28.7 t/ha), which was 10.0 and 7.0 t/ha more than in the control variant. The yield of ‘Summer Highland F1’ was 24.9 t/ha and ‘Suprin F1’ 24.6 t/ha. Under the conditions of unstable soil moisture, hybrids ‘Villi F1’and ‘Sprinkin F1’ appeared the most productive and ensured yield increase of 10.0 t/ha and 7.0 t/ha, respectively, compared to the control; and crop commercial quality was high. The highest percentage of dry matter (DM) content was in ‘Summer Highland F1’ (6.2%) followed by ‘Sprinkin F1’ (5.9%), which was 1.1% and 0.8% more than in the control. There was no significant difference between the values of the total sugars content over the variants. They ranged between 1.7 and 2.1%, which was similar to the control values. The content of nitrates in the cabbage heads of the studied Chinese cabbage hybrids was within the tolerance limit and amounted to 600 mg/kg (raw mass).Conclusions. Phenological observations of plant development and their biometric indices, depending on the varietal characteristics, indicate that under the conditions of unstable soil moisture, hybrids ‘Villi F1’ and ‘Sprinkin F1’ were more yielding and ensured yield increase of 10.0 t/ha and 7.0 t/ha, respectively, compared to the control. The crop commercial quality was high. The long growing season of ‘Richi F1’ (93 days) did not affect the crop quality and yield and demonstrated the lowest productivity compared to the control and the other experiment variants.

Purpose. Development of scientific and applied foundations for the introduction, selection and use of plants of the species of the genus Physalis L. to ensure food security in Ukraine. Methods. Subject of study – plants of the genus Physalis. The study was conducted in 2014–2018. on the introduction plots of the department of cultural flora of the M. M. Hryshko National Botanical Garden, NAS of Ukraine (NBG). The work used general scientific and special methods: field, introduction, biological and morphological; laboratory (chemical, biochemical), statistical (methods of analysis of variance and statistical estimation of average data using Microsoft Excel (2010). Results. The features of ontomorphogenesis were established, the biological and morphological parameters of plants of the species of the genus Physalis L. were investigated under conditions of introduction in the Right-Bank Forest-Steppe Ukraine. It was found that the content of dry matter in plant fruits varied from 10 to 18.34%, sugars – from 39.34 to 67.97%, tannins – 1.57 to 3.35% and carotene – from 0.200 to 0.583%, ascorbic acid – from 123.91 to 284.95 mg/100 g, depending on the species, varietal and shape characteristics. Conclusions. It was found that the introduced plant species of the genus Physalis in conditions of culture have four age periods and 10 developmental states: seeds (se), sprouts (p), juvenile (j), immature (im), virginal (v), generative (g), subsenilny (ss) and senile (se). Ph. ixocarpa ‘Likhtaryk’ of the NBG selection was distinguished among the studied introduced species in terms of biological and morphological parameters and biochemical composition. The obtained data can be used for further research and determining the prospects for the introduction of these introduced species into a wide culture

Purpose. Provide bioinformatic analysis and comparison of target regions of the acetolactate synthase (als) gene in several members of the Poaceae family and, on the basis of the obtained data, explore the possibility of creating a unified genetic construct for als gene editing using the CRISPR-Cas9 system. Methods. The als gene sequences of various members of the Poaceae family were obtained from the NCBI: Nucleotide database. For comparison, a fragment of the imi-2 gene of wheat of the soft line ‘TealIMI11A’ was used in two regions of the 367–390 and 1729–1749 nucleotide sequences. The Sequence Viewer 3.37.0 tool was used to assess the presence of nucleotide substitutions in the working sequence of the imi-2 gene. The dendrogram was built using the “Blast Tree” tool from the NCBI: Blast: Nucleotide resource. Results. A comparative analysis of the nucleotide sequences of seven different species was carried out: soft wheat (Triticum aestivum L.), common wild oat (Avena fatua L.), barley (Hordeum vulgare L.), Asian rice (Oryza sativa L.), maize (Zea mays L.), aleppo grass (Sorghum halepense Pers.) and Tausch’s goatgrass (Aegilops tauschii Coss.). The dendrogram is based on the gene sequence als, showed that all studied genotypes can be divided into two blocks: the first block included maize and aleppo grass, and the second block, a separate branch includes Asian rice and common wild oat, barley, soft wheat and Tausch’s goatgrass. 367–390 nucleotide sequences of soft wheat showed the highest 100% homology to Asian rice, Tausch’s goatgrass and common wild oat. The lowest homo­logy was for maize and aleppo grass at 83.3%. Evaluation of the nucleotide sequence 1729–1749 showed no complete homology at the 100% level. It was the highest for barley and Tausch’s goatgrass – 95.2%, and the lowest for rice, maize and aleppo grass – 80.9% each. Conclusions. The analysis confirms a significant degree of homology of the als gene sequence for various species of the Poaceae family, which allows us to create a universal genetic vector. However, taking into account the high degree of sequence homology for species such as soft wheat, Tausch’s goatgrass, barley, Asian rice and common wild oat, it can be assumed that the corresponding genetic vector can be used with the greatest efficiency to alter the als gene of these genotypes.

Провести биоинформатический анализ и сравнить целевые участки гена ацетолактат синтазы (als) у нескольких представителей семейства Злаковых и на основе полученных данных исследовать возможность создания унифицированной генетической конструкции для направленного изменения гена als с помощью системы CRISPR-Cas9.Методы. Сиквенсы гена als различных представителей семейства Злаковых были получены из базы данных NCBI: Nucleotide. Для сравнения был использован фрагмент гена imi-2 пшеницы мягкой линии ‘TealIMI11A’ в двух участках сиквенса 367–390 и 1729–1749 нуклеотидов. Для оценки наличия нуклеотидных замен в рабочих сиквенсах гена imi-2 использовали инструмент ‘Sequence Viewer 3.37.0’. Дендрограмму строили с использованием инструмента “Blast Tree” с ресурса NCBI: Blast: Nucleotide. Результаты. Был проведен сравнительный анализ нуклео­тидных последовательностей семи различных видов: пшеницы мягкой (Triticum aestivum L.), овсюга обыкновенного (Avena fatua L.), ячменя обыкновенного (Hordeum vulgare L.), риса посевного (Oryza sativa L.), кукурузы (Zea mays L.), сорго алепского (Sorghum halepense Pers.) и эгилопса Тауша (Aegilops tauschii Coss.). На основе сравнительного анализа сиквенса участков гена іmi-2 для 7-ми генотипов построили филогенетическое дерево, которое показало, что исследованные виды можно разделить на два блока. В первый блок вошли кукуруза и сорго алеппское, а ко второму блоку – рис посевной, овсюг обыкновенный, ячмень обыкновенный, пшеница мягкая и эгилопс Тауша. Определение степени гомологии между последовательностью 367–390 нуклеотида пшеницы мягкой и другими видами показала, что абсолютной была гомология с соответствующими последовательностями риса посевного, эгилопса Тауша и овсюга обыкновенного (100%). Наименьшим нуклеотидное родство оказалось для кукурузы и сорго алеппского – по 83,3%. На участке 1729–1749 нук­леотидов гена іmi-2 никакой из 6 сиквенсов не показал 100% гомологии с последовательностью пшеницы мягкой. Самой высокой она была для ячменя обыкновенного и эгилопса Тауша – 95,2%, а наименьшей для риса посевного, кукурузы и сорго алеппского – по 80,9%.Выводы. Проведенный анализ подтверждает значительную степень гомологии последовательности гена als для различных видов семейства Злаковых. Это позволяет допустить возможность создания универсальной генетической конструкции, с помощью которой можно осуществлять редактирование генома и получения растений, устойчивых к гербициду разных представителей этой семьи. Учитывая высокую степень гомологии последовательностей для таких видов как пшеница мягкая, эгилопс Тауша, ячмень обыкновенный, рис посевной и овсюг обыкновенный, можно предположить, что с наибольшей эффективностью соответствующая генетическая конструкция может быть использована для редактирования гена als именно этих генотипов. | Провести біоінформатичний аналіз та порівняти цільові ділянки гена ацетолактат синтази (als) у декількох представників родини Злакових і на основі отриманих даних дослідити можливість створення уніфікованої генетичної конструкції для направленого редагування гена als за допомогою системи CRISPR-Cas9. Методи. Сиквенси гена als різних представників родини Злакових було отримано з бази даних NCBI: Nucleotide. Для порівняння було використано фрагмент гена іmi-2 пшениці м’якої лінії ‘TealIMI11A’ у двох ділянках сиквенсу: 367–390 та 1729–1749 нук­леотидів. Для оцінювання наявності нуклеотидних замін в робочих сиквенсах гена іmi-2 використовували інструмент “SequenceViewer 3.37.0”. Дендрограму будували з використанням інструменту ‘BlastTree’ з ресурсу NCBI: Blast: Nucleotide. Результати. Було проаналізовано нуклеотидні послідовності сімох різних видів: пшениці м’якої (TriticumaestivumL.), вівсюга звичайного (AvenafatuaL.), ячменю звичайного (HordeumvulgareL.), рису посівного (OryzasativaL.), кукурудзи (ZeamaysL.), сорго алепського (SorghumhalepensePers.) та егілопса Тауша (AegilopstauschiiCoss.). На основі порівняльного аналізу сиквенсу ділянок гена іmi-2 для 7-ми генотипів було побудовано філогенетичне дерево, яке показало, що досліджені види можна поділити на два блоки. До одного з них увійшли кукурудза та сорго алепське, а до другого – рис посівний, вівсюг звичайний, ячмінь звичайний, пшениця м’яка та егілопс Тауша. Визначення ступеня гомології між послідовністю 367–390 нуклеотиду пшениці м’якої та іншими видами показало, що абсолютною була гомологія з відповідними послідовностями рису посівного, егілопса Тауша та вісюга звичайного (100%). Найменшою нуклеотидна спорідненість виявилась для кукурудзи та сорго алепського – 83,3%. У ділянці 1729–1749 нуклеотидів гена іmi-2 жоден з 6 сиквенсів не показав 100% гомології з послідовністю пшениці м’якої. Найвищою вона була до ячменю звичайного та егілопсу Тауша – 95,2%, а найменшою для рису посівного, кукурудзи та сорго алепського – по 80,9%. Висновки. Проведений аналіз підтверджує значний ступінь гомології послідовності гена als для різних видів родини Злакових. Це дозволяє зробити припущення про можливість створення універсальної генетичної конструкції, за допомогою якої можна редагувати геном та отримувати рослини, стійкі до гербіцидів різних представників цієї родини. Зважаючи на вищий ступінь гомології послідовностей для таких видів як пшениця м’яка, егілопс Тауша, ячмінь звичайний, рис посівний та вівсюг звичайний, можна припустити, що ефективнішою відповідна генетична конструкція буде для редагування гена als саме цих генотипів.

Purpose. Analysis of the allelic state of Ppd-1 genes, which control sensitivity to photoperiod, in varieties and lines of bread winter wheat, and comparison of the results obtained with field observations on the duration of periods before heading and flowering, whose originators were the Nosivska Breeding and Research Station of the V. M. Remeslo Myronivka Institute of Wheat National Academy of Agrarian Sciences of Ukraine and Poltava State Agrarian Academy of the Ministry of Education and Science of Ukraine. Methods. The following methods were used in the work: DNA extraction, allele-specific PCR, agarose and polyacrylamide gel electrophoresis, analysis of variance. Results. It was revealed that ‘Yuvivata 60’ variety has a recessive Ppd-1 genotype and belongs to the III haplotype by a combination of mutations in the structure of Ppd-D1 gene. Line ‘L41/95’ was heterogeneous by alleles of Ppd-D1 gene, which corresponded to the presence of haplotypes III and VII. All other tested cultivars and lines were characterized by alleles Ppd-A1b, Ppd-B1b and Ppd-D1a, and assigned to haplotype VII. According to the results of statistical data processing, the duration of the period from May, 1 to heading was the smallest for the variety ‘Donskaya polukarlikovaya’ in the conditions of both the Forest-Steppe and Polissia-Forest-Steppe regions of Ukraine, the longest – in the varieties ‘Yuvivata 60’, ‘Myronivska 61’ and ‘L41/95’. The differences between these groups were significant and amounted to 10 days. Conclusions. A breeding material with a high adaptive ability for growing conditions in Polissia-Forest-Steppe zone was studied by the allelic state of the Ppd-1 genes. A low level of polymorphism in the studied varieties and lines was revealed by the alleles of Ppd-1 genes [12.5% – Ppd-D1b (²²²), 12.5% – Ppd-D1à/b (²²²/VII), 75% – Ppd-D1a (VII)], that agrees with the hypothesis that breeders gave a greater preference for the photoperiod-insensitive wheat genotype under Ukrainian conditions. The genotypes with the dominant Ppd-D1a (VII) gene almost completely dominate in the south of Ukraine. At the same time, in northern latitudes, weather conditions negate the advantages of the genotypes with Ppd-D1a gene

Визначення алельного стану генів Ppd-1, що контролюють чутливість до фотоперіоду, у сортів та ліній пшениці м’якої озимої Носівської селекційно-дослідної станції Миронівського інституту пшениці ім. В. М. Ремесла НААН (НСДС МІП) і Полтавської державної аграрної академії МОН України (ПДАА), та зіставлення отриманих результатів молекулярно-генетичного аналізу з даними польових спостережень щодо строків колосіння та цвітіння.Методи. Виділення ДНК, алель-специфічна ПЛР, електрофорез фрагментів ампліфікації в агарозних та полі­акриаламідних гелях, дисперсійний аналіз.Результати. Визначено, що сорт ‘Ювівата 60’ має рецесивний генотип Ppd-1 та належить до ІІІ гаплотипу за комбінацією мутацій у структурі Ppd-D1 гена. Лінія ‘Л41/95’ виявилася гетерогенною за алелями гена Ppd-D1, що відповідало наявності гаплотипів III і VII. Усі інші досліджені зразки характеризувалися алелями Ppd-A1b, Ppd-B1b та Ppd-D1а та належали до гаплотипу VII. За результатами статистичної обробки даних тривалість періоду від першого травня до колосіння була найменшою в сорту ‘Донская полукарликовая’ в умовах як Лісостепу, так і Полісся–Лісостепу Ук­раїни, найбільшою – у сортів ‘Ювівата 60’, ‘Миронівська 61’ та лінії ‘Л41/95’. Відмінності між зазначеними групами були достовірними й становили приблизно 10 діб.Висновки. За алельним станом генів Ppd-1 досліджено селекційний матеріал з високою адаптивною здатністю для умов вирощування в перехідній зоні Полісся–Лісостеп. За алелями генів Ppd-1 досліджені сорти та лінії виявили невисокий рівень поліморфізму [12,5% – Ppd-D1b (ІІІ), 12,5% – Ppd-D1а/b (ІІІ/VII), 75% – Ppd-D1a (VII)], що узгоджується з гіпо­тезою надання селекціонерами більшої переваги слабкочутливим до фотоперіоду генотипам пшениці в умовах України. Генотипи з домінантним алелем Ppd-D1a (VII) в умовах Півдня України практично повністю домінують. Водночас у північніших широтах погодні умови нівелюють переваги, що мають генотипи з Ppd-D1a.

It was revealed that ‘Yuvivata 60’ variety has a recessive Ppd-1 genotype and belongs to the III haplotype by a combination of mutations in the structure of Ppd-D1 gene. Line ‘L41/95’ was heterogeneous by alleles of Ppd-D1 gene, which corresponded to the presence of haplotypes III and VII. All other tested cultivars and lines were characterized by alleles Ppd-A1b, Ppd-B1b and Ppd-D1a, and assigned to haplotype VII. According to the results of statistical data processing, the duration of the period from May, 1 to heading was the smallest for the variety ‘Donskaya polukarlikovaya’ in the conditions of both the Forest-Steppe and Polissia-Forest-Steppe regions of Ukraine, the longest – in the varieties ‘Yuvivata 60’, ‘Myronivska 61’ and ‘L41/95’. The differences between these groups were significant and amounted to 10 days. Conclusions. A breeding material with a high adaptive ability for growing conditions in Polissia-Forest-Steppe zone was studied by the allelic state of the Ppd-1 genes. A low level of polymorphism in the studied varieties and lines was revealed by the alleles of Ppd-1 genes [12.5% – Ppd-D1b (²²²), 12.5% – Ppd-D1à/b (²²²/VII), 75% – Ppd-D1a (VII)], that agrees with the hypothesis that breeders gave a greater preference for the photoperiod-insensitive wheat genotype under Ukrainian conditions. The genotypes with the dominant Ppd-D1a (VII) gene almost completely dominate in the south of Ukraine. At the same time, in northern latitudes, weather conditions negate the advantages of the genotypes with Ppd-D1a gene

Purpose. To determine the level of productivity of sunflower hybrids, their stability and plasticity for cultivation in the Left Bank Forest-Steppe of Ukraine. Methods. The field experiment was performed in the conditions of the Left-Bank Forest-Steppe of Ukraine in 2016–2018. The peculiarities of plant growth and development, formation of yield of hybrids ‘Ukrainskyi F1’ (k), ‘P64LL125’, ‘P63LE10’, ‘P64F50’, ‘P64F66’, ‘P63LL06’, ‘NK Konti’ (k), ‘NK Brio’, ‘P64LE99’, ‘Laskala’, ‘Kupava’. Yield plasticity was calculated and analyzed by the Ebergard – Russell method. Results. Over the years of research, the average yield of sunflower hybrids in the Left-Bank Forest-Steppe of Ukraine varied from 2.71 to 4.04 t/ha. The lowest yield was shown by the ‘Ukrainskyi F1’ hybrid – 2.42–3.05 t/ha, the highest ‘Laskala’ – 3.79–4.26 t/ha. It was determined that in the conditions of the Left-Bank Forest-Steppe, there is no absolute predominance of medium-ripe hybrids in terms of yield. Conclusions. According to the results of the analysis of yield plasticity of sunflower hybrids, it was determined that the group of samples with high yield plasticity includes ‘Ukrainskyi F1’, ‘P64F50’, ‘P64F66’, ‘NK Konti’, ‘NK Brio’, ‘P64LE99’, ‘Lascala’ and ‘Kupava’. They respond to the improvement of the level of agricultural technology and provide the maximum yield only under the conditions of optimal factors. Hybrids ‘P64LL125’, ‘P63LE10’ and ‘P63LL06’ are more stable in response to changes in growing conditions without reductions in yield. As for the shares of the influence of the studied factors, the yield of the hybrid ‘Ukrainskyi F1’ was most influenced by the conditions of the year, ‘NK Brio’ – the sowing rate. For the ‘NK Ferti’ hybrid, the conditions of the year and the sowing rate are equally important.
