Purpose. Morphological and organoleptic evaluation of oyster mushroom strains for selection of highly productive cultivars assortment with valuable consumer properties for winter and summer cultivation and suitability for sale in fresh or processed form were investigated. Methods. The scheme of the experiment included six strains of oyster mushrooms belonging to two species: Pleurotus ostreatus (5 strains: 2301, Z, 2316, 2456, 431) and P. pulmonarius (2314). Laboratory, laboratory-industrial and statistical methods are used. Results. The dynamics of agrochemical parameters of substrates obtained by the method of aerobic fermentation in the high layer proved their optimality according to the main criteria and compliance to regulatory documentation. The biological efficiency of the strains was in the range of 40–78.9%. The highest weight of clusters was found in the “summer” strain 431 (430.7 g). The highest weight of the fruiting body was determined for the strain 2301 (15.2 g), the lowest – for the 2456 (3.3 g). Conclusions. The values of biological efficiency of strains was determined. The highest average values for the first flush of fruiting had strains 2316 (78.9%) from the “winter” group (A) and 431 (78.4%) from the “summer” group (B). According to the results of statistical analysis, significant differences were revealed between the studied strains in the main morphological indicators of clusters. It was found that the mass of clusters of «winter» cultivars is much less dependent on the strain type (220.8–273.4 g) than that of «summer» cultivars (83.4–430.7 g). The index of the asymmetry coefficient of the cluster, which can be useful for calculating the required container sizes was proposed. It was determined that the morphological features of fruiting bodies had significant differences in all studied parameters. In particular, the A group strains differed in size and weight. It was proposed the index of weight loss of the crop coefficient, which shows the ratio between the cap and stipe of the fruiting body and make it possible to predict the amount of mushroom raw material that will be sold in the form of caps, and the amount of raw material that can be processed into minced mushroom, powder and others. The best coefficient was obtained for the fruiting bodies of strain 2314 (0.87), and the worst – for 2456 (0.59), which, accordingly, is not recommended for sale by individual fruiting bodies. It was found that the fruiting bodies of high-yielding strains 2316 and 431 had a number of organoleptic defects.

Purpose. To evaluate Tartary buckwheat variety ‘Kalyna’ according to morphological, productive and quality indicators in the conditions of the Research Center “State Agra­rian and Engineering University in Podilia”. Methods. The studies were carried out in the field crop rotation of the Research Center “Podillia” of the State Agrarian and Engi­neering University in Podilia (SAEU) in 2015–2020. The soil cover of the experimental field is represented mainly by low-humus, weakly leached soils. Experiment setting, material evaluation, analysis of plants, yield and grain quality were carried out in accordance with the generally accepted methods of state variety testing. An assessment of the Tartary buckwheat variety ‘Kalyna’ was carried out in comparison with the common buckwheat variety ‘Victoriia’. Results. The growing season duration of Tartary buckwheat variety ‘Kalyna’ was 87 days (38 days vegetative and 49 days gene­rative). In the studied variety, a larger number of the 1st order branches up to 5.5 pcs was observed. The number of leaves on the plant was 22–28 pcs./plants. In the studied variety, more than 50% of the grains were located on the main stem and the first order branches, while in common buckwheat this indicator was only 30%. Productivity was 2,28 t/ha, the number of grains in inflorescences was 4,4 grains, in common buckwheat – 0,72 t/ha, and 2.2 grains/inflorescence, respectively. The thousand kernel weight in Tartary buckwheat variety ‘Kalyna’ is 10.2 g less than in common buckwheat variety ‘Victoriia’ and is 17.4 g, with hulls – 19.5%, which is 3.2% less then in common buckwheat variety.Assessment of Tartary buckwheat variety ‘Kalyna’ for resistance to the effects of bio- and abiotic factors indicates that it was at the level of common buckwheat variety ‘Victoriia’.In terms of resistance to abiotic factors, ‘Kalyna’ variety is characterized by high resistance to spontaneous fallof grain (5 scores) and has simultaneous grain ripening (5 scores). Conclusions.The morphological and economic-biological indicators of Tartary buckwheat variety ‘Kalyna’ are significantly higher than the common buckwheat varie­ty ‘Victoriia’. It is recommended to grow Tartary buckwheat variety ‘Kalyna’ as a valuable cereal crop in the Western Forest-Steppe zone.

Purpose. To study the expression of gus and gfp genes in callus explants of amphidiploid spelt wheat (Triticum spelta L.) after Agrobacterium-mediated genetic transformation. Methods. Winter spelt wheat of ‘Europa’ variety was chosen for transformation. Calli obtained from mature embryos were used as explants. Callus pre-cultivation was carried out on MS nutrient medium (Murashige–Skoog) supplemented with 2 mg/L 2.4-D (2.4-Dichlorophenoxyacetic acid) and 10 mg/L silver nitrate. For genetic transformation, Agrobacterium tumefaciens Conn., strain GV3101 and a genetic construct with reporter genes beta-glucuronidase (GUS) and green fluorescent protein (GFP) were used. Calli were transformed by inoculation with agrobacteria and vacuum infiltration. Then they were co-cultured on MS medium with 2 mg/L 2.4-D and 10 mg/L AgNO3, but without antibiotics. The expression of the gus gene was checked by histochemical and the gfp gene by visual analysis (fluorescence of the GFP protein in UV light). Gfp and gus gene expression levels were evaluated using ImajeJ software. The integration of the gfp and gus genes into the spelt genome was verified by PCR. Results. Genetic transformation of spelt callus explants by inoculation in a nutrient medium with agrobacteria and vacuum infiltration occurred at different frequencies. The level of expression of the gus gene during vacuum infiltration was 4.66 ± 0.74%, with inoculation – 4.00 ± 0.91%; and the gfp gene with vacuum infiltration – 3.66 ± 0.74%, with inoculation – 4.66 ± 1.39%. The level of expression of the gfp gene was higher when using inoculation with agrobacteria, and the gus gene was higher during vacuum infiltration. Using PCR analysis, the integration of the gfp and gus genes into the callus of spelt genome was confirmed. The length of the PCR product with primers for the gus gene was 240 bp, and 717 bp for the gfp gene. Conclusions. The use of vacuum infiltration and inoculation methods for spelt genetic transformation gave different results. The frequency of genetic transformation ranged from 3.66 to 4.66%. Agrobacterium-mediated genetic transformation of amphidiploid spelt wheat allows us to study the expression of gus and gfp reporter genes using callus explants derived from mature embryos

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 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.

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.

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. Изучить сорта сои различного происхождения по содержанию белка и других хозяйственно ценных признаках, определить показатели стабильности и пластичности этих признаков, а также выделить сорта, перспективные для использования в селекционных программах.Методы. 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. Программно-аппаратный комплекс должен иметь обратную связь между его основными структурными элементами, ведь за счет этого значительно повышается точность прогнозирования продуктивности растений. Данные полученные на основе работы определенных механизмов или показатели погодных условий и их прогнозы используются для принятия решений, однако, в случае их существенного изменения решение об отдельных элементах технологии пересматриваются. 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. Выводы. Адаптивная информационная система прогнозирования продуктивности в технологическом процессе выращивания сельскохозяйственных культур формируется на базе модели состоящей из трех модулей признаков – результирующей и двух компонентных. На каждом следующем этапе реализации модели результирующий признак становится компонентным, причем с максимальным вкладом в результирующий признак следующего модуля. | Purpose of this study was to develop the main components of a model of an adaptive information system for predicting crop productivity.

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. Программно-аппаратный комплекс должен иметь обратную связь между его основными структурными элементами, ведь за счет этого значительно повышается точность прогнозирования продуктивности растений. Данные полученные на основе работы определенных механизмов или показатели погодных условий и их прогнозы используются для принятия решений, однако, в случае их существенного изменения решение об отдельных элементах технологии пересматриваются. 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.Выводы. Адаптивная информационная система прогнозирования продуктивности в технологическом процессе выращивания сельскохозяйственных культур формируется на базе модели состоящей из трех модулей признаков – результирующей и двух компонентных. На каждом следующем этапе реализации модели результирующий признак становится компонентным, причем с максимальным вкладом в результирующий признак следующего модуля.

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.
