Purpose. To establish the optimal seeding time and depth of ‘Dniprovskyi 39’ and ‘Vinets’ sorghum varieties, to prove their effect on the crop photosynthetic capacity in the Right-Bank Forest-Steppe of Ukraine. Methods. Field, laboratory, comparative, analytical, generalizing, mathematical and statistical. Results. It was proved that the best results of crop photosynthetic capacity of sorghum were obtained by sowing in the first decade of May (the second sowing period) at a seeding depth of 4–6 cm. Accordingly, the leaf surface area in these variants reached its maximum during the “panicle-blooming” period and equated 36.13–38.81 thousand m2/ha for the ‘Dniprovskyi 39’ variety and 34.23–36.91 thousand m2/ha for the ‘Vinets’ variety. By sowing seeds in the third decade of April (the first sowing period) at the seedining depth values described above the leaf surface area of the varieties was slightly smaller and amounted to 29.56–31.20 thousand m2/ha for the ‘Dniprovskyi 39’ variety and 27.76–29.40 thousand m2/ha for the ‘Vinets’ variety. By sowing seeds in the second decade of May (the third sowing period), the leaf surface area was 30.68–32.92 thousand m2/ha for the ‘Dniprovskyi 39’ variety and 29.08–31.32 thousand m2/ha for the ‘Vinets’ variety. The highest photosynthetic potential was obtained for sorghum plants in the second sowing period at the seeding depth of 4–6 cm and was 1.27 and 1.34 million m2/ha for the ‘Dniprovskyi 39’ variety and 1.16 and 1.22 million m2/ha for the variety ‘Vinets’. In the first sowing period, this indicator was slightly lower and amounted to 1.18 and 1.23 million m2/ha for the ‘Dniprovskyi 39’ variety and 0.98 and 1.02 million m2/ha for the ‘Vinets’ variety respectively. In the third sowing period, it was the smallest one and equated 1.09 and 1.13 million m2/ha for the ‘Dniprovskyi 39’ variety, and 0.88 and 0.93 million m2/ha for the ‘Vinets’ variety at the optimal seeding depth. The photosynthetic potential was lower at the seeding depth of 2 and 8 cm, which is explained by the different soil and climatic parameters during a certain period of sorghum plant vegetation. The highest value of the photosynthetic capacity net indicator was obtained by sowing seeds at the optimal time and the optimal seeding depth and it equated 3.84–4.02 g/m2 per day for the ‘Dniprovskyi 39’ variety and 3.79 – 3.98 g/m2 per day for the ‘Vinets’ variety. Conclusions. It has been established that the sorghum plants had better vegetation and formed photosynthetic capacity by sowing seeds in the first decade of May at the planting depth of 4–6 cm, which we recommend for growing this crop in the Right-Bank Forest-Steppe of Ukraine.

Цель. Установить оптимальные сроки сева и глубину заделки семян сорго зернового сортов ‘Дніпровський 39’ и ‘Вінець’, обосновать их влияние на фотосинтетическую продуктивность посевов в условиях Правобережной Лесостепи Украины.Методы. Полевой, лабораторный, сравнительный, аналитический, обобщающий, математически-статистический.Результаты. Наилучшие результаты фотосинтетической продуктивности посевов сорго зернового получены во время сева в I декаде мая (второй срок) на глубине заделки семян 4–6 см. Соответственно, площадь листовой поверхности в этих вариантах в период «выбрасывания метелки–цветения» достигала максимума и составляла 36,13–38,81 тыс. м2/га у сорта ‘Дніпровський 39’ и 34,23 – 36,91 тыс. м2/га у сорта ‘Вінець’. При севе семян в III декаде апреля (первый срок) при вышеуказанных значениях глубины заделки площадь листовой поверхнос­ти у сортов была несколько меньше и составляла 29,56–31,20 тыс. м2/га у сорта ‘Дніпровський 39’ и 27,76–29,40 тыс. м2/га у сорта ‘Вінець’. При севе семян во II декаде мая (третий срок) площадь листовой поверхности составляла 30,68–32,92 тыс. м2/га у сорта ‘Дніпровський 39’ и 29,08–31,32 тыс. м2/га у сорта ‘Вінець’. Фотосинтетический потенциал был самым высоким в растениях сорго зернового во втором сроке сева семян на глубине заделки 4–6 см и составлял 1,27 и 1,34 млн м2/га у сорта ‘Дніпровський 39’ и 1,16 и 1,22 млн м2/га у сорта ‘Вінець’. В первом сроке сева этот показатель был несколько ниже и составлял 1,18 и 1,23 млн м2/га у сорта ‘Дніпровський 39’ и 0,98 и 1,02 млн м2/га у сорта ‘Вінець’, соответственно. В третьем сроке сева он был самым низким, у сорта ‘Дніпровський 39’ этот показатель составлял 1,09 и 1,13 млн м2/га, у сорта ‘Вінець’ – 0,88 и 0,93 млн м2/га при оптимальных значениях глубины заделки семян. На глубине заделки семян 2 и 8 см фотосинтетический потенциал был ниже, что объясняют различными почвенно-климатическими условиями в определенный период развития растений сорго. Наивысшее значение показателя чистой продуктивности фотосинтеза было получено при севе семян в оптимальные сроки и оптимальной глубине заделки семян и составляло 3,84–4,02 г/м2 в сутки у сорта ‘Дніпровський 39’ и 3,79–3,98 г/м2 в сутки у сорта ‘Вінець’, соответственно.Выводы. Лучше развивались и формировали фотосинтетическую продуктивность растения сорго зернового при севе семян в первой декаде мая на глубине заделки 4–6 см, которые и рекомендованы для выращивания данной культуры в Правобережной Лесостепи Украины. | Purpose.

Встановити оптимальні строки сівби та глибину загортання насіння сорго зернового сортів ‘Дніпровський 39’ та ‘Вінець’, обґрунтувати їхній вплив на фотосинтетичну продуктивність посівів в умовах Правобережного Лісостепу України. Методи. Польовий, лабораторний, порівняльний, аналітичний, узагальнюючий, математично-статистичний. Результати. Найкращі результати фотосинтетичної продуктивності посівів сорго зернового отримано за сівби у  І декаді травня (другий строк) на глибину загортання насіння 4–6 см. Відповідно, площа листкової поверхні за цих факторів у період «викидання волоті – цвітіння» сягала максимуму і дорівнювала 36,13–38,81 тис. м2/га у сорту ‘Дніпровський 39’ та 34,23–36,91 тис. м2/га у сорту ‘Вінець’. За сівби насіння у ІІІ декаді квітня (перший строк) за таких самих значень глибини загортання площа листкової поверхні у сортів була дещо меншою і становила 29,56–31,20 тис. м2/га у сорту ‘Дніпровський 39’ та 27,76–29,40 тис. м2/га у сорту ‘Вінець’. За сівби насіння у ІІ декаді травня (третій строк) площа листкової поверхні дорівнювала 30,68–32,92 тис. м2/га у сорту ‘Дніпровський 39’ та 29,08–31,32 тис. м2/га у сорту ‘Вінець’. Фотосинтетичний потенціал був найвищим у рослин сорго зернового за ІІ строку сівби насіння та глибини загортання 4–6 см й дорівнював 1,27 та 1,34 млн м2/га у сорту ‘Дніпровський 39’ і 1,16 та 1,22 млн м2/га у сорту ‘Вінець’. За І строку сівби цей показник був дещо меншим і відповідно становив 1,18 та 1,23 млн м2/га у сорту ‘Дніпровський 39’ й 0,98 і 1,02 млн м2/га у сорту ‘Вінець’. За ІІІ строку сівби він був найменшим та у сорту ‘Дніпровський 39’ дорівнював 1,09 і 1,13 млн м2/га, у сорту ‘Вінець’ 0,88 і 0,93 млн м2/га за оптимальних значень глибини загортання насіння. За глибини загортання насіння 2 та 8 см фотосинтетичний потенціал був нижчим, що пояснюють різними ґрунтово-кліматичними умовами у певний період розвитку рослин сорго. Найбільше значення показника чистої продуктивності фотосинтезу було отримано за сівби насіння в оптимальні строки та за оптимальної глибини загортання насіння і становило у сорту ‘Дніпровський 39’, відповідно, 3,84–4,02 г/м2 за добу, у сорту ‘Вінець’ 3,79–3,98 г/м2 за добу.Висновки.

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.

We calculated and analyzed the sums of active, effective temperatures for two biological minima - 5 and 10 ° C; the sum of thermal units according to the method of Brown and Bootsma, 1993; coefficients of materiality of elements deviations of the agrometeorological mode of the current year from long-term averages; plasticity and yield stability according to the method of Eberthart S.A., Russel W.Q. (1966). Results. To pass the full cycle of sunflower plants development, the sum of active temperatures (t = 10 °C) for hybrid 'Ukrainskyi F1' – 2354.6; P63LL06 – 2306.4; 'NK Brio' – 2401.3; 'NK Ferti' – 2379.7; and the sum of effective temperatures for 'Ukrainskyi F1'- 1081.5; 'P63LL06' – 1056.9; 'NK Brio' – 1104.9; 'NK Ferti' – 1109.1 is required. The sum of temperatures, both at a biological minimum temperature 10 °C and 5 °C, meet biological needs of sunflower plants and is not a limiting factor for this crop growing. The sum of thermal units for the period April–October is 3780 on average for three years. During the period of active sunflower vegetation (April–August) the sum of thermal units is 2868–3258, significantly exceeding the sum of active and effective temperatures at biologically active temperatures 5 °С and 10 °С. The most determined limits of changes in active, effective temperatures and thermal units were observed in May – September. Conclusions. Plasticity and stability of sunflower yield more depending on hybrid and plants density than on conditions of the year. Yield stability coefficient for hybrid 'Ukrainskyi F1' was 1.68 - 2.30; 'P63LL06'- 2.51 - 3.14; 'NK Brio'- 3.15 - 4.63; 'NK Ferti' - 2.70 - 3.75 for yields, respectively: 2.16 - 3.11; 2.58 - 3.52; 3.20 - 4.12; 2.70 - 3.79 t/ha.

Plasticity and stability of sunflower yield more depending on hybrid and plants density than on conditions of the year. Yield stability coefficient for hybrid 'Ukrainskyi F1' was 1.68 - 2.30; 'P63LL06'- 2.51 - 3.14; 'NK Brio'- 3.15 - 4.63; 'NK Ferti' - 2.70 - 3.75 for yields, respectively: 2.16 - 3.11; 2.58 - 3.52; 3.20 - 4.12; 2.70 - 3.79 t/ha. | Мета. Встановити відповідність ресурсів тепла та вологи біологічним вимогам гібридів соняшнику (Helianthus annuus L.); встановити критеріальні показники оцінювання погодних умов в північних регіонах України; встановити зв’язки між температурним режимом, сумою опадів та врожайністю.Методи. Використовували польовий та математичний методи. Польовий багатофакторний дослід проводили в 2016–2018 роках в Лівобережному Лісостепу України на межі двох ґрунтово-кліматичних зон – Лісостепу і Полісся. Досліджували особливості росту та розвитку рослин, формування врожайності «гібридів» (фактор А) ‘Український F1’, ‘Р63LL06’, ‘НК Бріо’, ‘НК Ферті’ залежно від «густоти рослин» (фактор В): 50, 55, 60, 65 тис. шт./га. Розраховували й аналізували суми активних та ефективних температур за двома біологічними мінімумами – 5 і 10 °С; суми теплових одиниць за методикою Brown and Bootsma (1993); коефіцієнти суттєвості відхилень елементів погоди поточного року від середніх багаторічних; пластичність і стабільність урожайності за методикою Eberthart S. A., Russel W. Q. (1966).Результати. Для проходження повного циклу розвитку рослин соняшнику необхідна сума активних температур (tб.м. = 10 °C) для гібрида ‘Український F1’ – 2354,6; ‘Р63LL06’ – 2306,4; ‘НК Бріо’ – 2401,3; ‘НК Ферті’ – 2379,7; сума ефективних температур: ‘Український F1’ – 1081,5; ‘Р63LL06’ – 1056,9; ‘НК Бріо’ – 1104,9; ‘НК Ферті’ – 1109,1. Суми температур як за температурою біологічного мінімуму 10 °C, так і 5 °C, відповідають біологічним потребам рослин соняшнику і не є обмежувальним чинником для вирощування. Сума теплових одиниць за період квітень–жовтень складала в середньому за три роки 3780. За період активної вегетації соняшнику (квітень–серпень) сума теплових одиниць складала 2868–3258, суттєво перевищуючи суму активних та ефективних температур за біологічно активних температур 5 °С і 10 °С. Найбільш детерміновані межі змін активних, ефективних температур і теплових одиниць спостерігали в період травень–вересень.Висновки. Пластичність і стабільність урожайності соняшнику більше змінюються залежно від гібрида і густоти рослин, ніж від умов року. Коефіцієнт стабільності врожайності для гібрида ‘Український F1’ склав 1,68–2,30; ‘Р63LL06’ – 2,51–3,14; ‘НК Бріо’ – 3,15–4,63; ‘НК Ферті’ – 2,70–3,75 за урожайності 2,16–3,11; 2,58–3,52; 3,20–4,12; 2,70–3,79 т/га, відповідно. | Цель. Установить соответствие ресурсов тепла и влаги биологическим потребностям гибридов подсолнечника (Helianthus annuus L.); установить критериальные показатели оценивания погодных условий в северных регионах Украины; установить связь между температурным режимом, осадками и урожайностью.Методы. Использовали полевой и математический методы. Полевой многофакторный опыт проводили в 2016–2018 годах в Левобережной Лесостепи Украины. Исследовали особенности роста и развития растений, формирования урожайности «гибридов» (фактор А): ‘Украинский F1’, ‘Р63LL06’, ‘НК Брио’, ‘НК Ферти’ в зависимости от «густоты стояния растений» (фактор В): 50, 55, 60, 65 тыс. штук/га. Рассчитывали и анализировали суммы активных, эффективных температур по  двум биологическим минимумам – 5 и 10 °С; суммы тепловых единиц по методике Brown and Bootsma (1993); коэффициенты существенности отклонений погодных условий от средних многолетних данных; пластичность и стабильность урожайности по методике Eberthart S. A., Russel W. Q. (1966).Результаты. Для прохождения полного цикла развития растений подсолнечника, необходима сумма активных температур (tб.м. = 10 °C) для гибрида ‘Украинский F1’ – 2355; ‘Р63LL06’ – 2306; ‘НК Брио’ – 2401; ‘НК Ферти’ – 2380; сумма эффективных температур: ‘Украинский F1’ – 1082; ‘Р63LL06’ – 1057; ‘НК Брио’ – 1104,9; ‘НК Ферти’ – 1109. Суммы температур как при биологическом минимуме 10 °C, так и 5 °C, соответствуют биологическим требованиям растений подсолнечника и не являются лимитирующим фактором для выращивания. Сумма тепловых единиц за период апрель–октябрь составляла в среднем за три года – 3780. В период активной вегетации подсолнечника (апрель–август) сумма тепловых единиц составляла 2868–3258 и существенно превышала сумму активных и эффективных температур при биологически активных температурах 5 °С и 10 °С. Наиболее детерминированные границы изменений активных, эффективных температур и тепловых единиц наблюдали в мае–сентябре.Выводы. Пластичность и стабильность урожайности подсолнечника больше изменяются в зависимости от гибрида и густоты стояния растений, чем от погодных условий года. Коэффициент стабильности урожайности для гибрида ‘Украинский F1’ составил 1,68–2,30; ‘Р63LL06’ – 2,51–3,14; ‘НК Брио’ – 3,15–4,63; ‘НК Ферти’ – 2,70–3,75 при урожайности 2,16–3,11; 2,58–3,52; 3,20–4,12; 2,70–3,79 т/га соответственно.

Purpose. To substantiate the features of the classification of morphobiological and economically valuable indicators of highbush blueberry varieties of Vaccinium corymbosum L. Methods. The studies were carried out during 2012–2019. Research methods: field (visual examination of the manifestation of morphological signs of vegetative and generative organs of blueberry plants), laboratory (determination of the content of vitamin C, total sugar, pectin, carotenes, anthocyanins, flavonoids, total acidity in berries), analytical, comparative, statistical (cluster analysis). Results. Over the years of research, varieties of highbush blueberries were characterized by a stable manifestation of homogeneous morphological traits and economically valuable performance indicators. In particular, the studied varieties are classified according to ripeness groups: very early: ‘Fiolent’; early: ‘Draper’, ‘Huron’, ‘Clockwork’, ‘Cargo’, ‘Laska’; medium: ‘Blue Ribbon’, ‘Top shelf’, ‘ZF08-070’, ‘Mavka’; late: ‘Liberti’, ‘Last Call’ and very late: ‘Aurora’, ‘Overtime’. It was determined that the quantitative morphological traits of highbush blueberry varieties that influenced the formation of plant productivity include such traits as growth vigor, leaf length, leaf width, inflorescences lengthwise, bunch density, fruit size. Economically valuable indicators of suitability of highbush blueberry varieties remained stable within the ripeness group. The highest yield (19.5 t/ha) was provided by the mid-season variety ‘Mavka’ of domestic selection. The yield of berries from the bush of this variety was also high and amounted to 7 kg. The studied performance indicators were low in the variety ‘Blue Ribbon’ – 10.2 t/ha and 2.4 kg, respectively. The minimum and maximum values of the manifestation of characteristics will serve to establish the limiting boundaries of its variation in the next modeling of economically valuable indicators of highbush blueberry varieties. Conclusions. Such morphobiological characteristics of highbush blueberry varieties, as plant growth vigor, leaf length, leaf width, inflorescences lengthwise, bunch density, fruit size are closely related to plant productivity, berry yield per bush, berry weight and yield. Therefore, they can be involved in the development and improvement of the model of suitability indicators of highbush blueberries for distribution in Ukraine.

Мета. Обґрунтувати особливості класифікації морфобіологічних та господарсько-цінних показників сортів лохини високорослої Vaccinium corymbosum L. Методи. Дослідження проводили впродовж 2012–2019 рр. Методи дослідження: польовий (візуальне обстеження прояву морфологічних ознак вегетативних і генеративних органів рослин лохини), лабораторний (визначення вмісту в ягодах вітаміну С, загального цукру, пектину, каротинів, антоціанів, флавоноїдів, загальної кислотності), аналітичний, порівняльний, статистичний (кластерний аналіз).Результати. Сорти лохини високорослої за роки досліджень характеризувались стабільним проявом однорідних морфологічних ознак та господарсько-цінних показників продуктивності. Зокрема, досліджувані сорти класифіковані за групами стиглості: дуже рання: ‘Фіолент’; рання: ‘Драпер’, ‘Гурон’, ‘Клокворк’, ‘Карго’, ‘Ласка’; середня: ‘Блу ріббон’, ‘Топ шелф’, ‘ЗФ08070’, ‘Мавка’; пізня: ‘Ліберті’, ‘Ласт колл’ та дуже пізня: ‘Аврора’, ‘Овертайм’. Установлено, що до кількісних морфологічних ознак сортів лохини високорослої, які впливали на формування продуктивності рослин, належать такі ознаки, як сила росту, листок за довжиною, листок за шириною, суцвіття за довжиною, гроно за щільністю, плід за розміром. Господарсько-цінні показники придатності сортів лохини високорослої залишалися стабільними в межах групи стиглості. Найвищу врожайність (19,5 т/га) забезпечив середньостиглий сорт ‘Мавка’ вітчизняної селекції. Вихід ягід з куща в цього сорту був теж найвищим і становив 7 кг. Найнижчими досліджувані показники продуктивності були в сорту ‘Блу ріббон’ – 10,2 т/га і 2,4 кг відповідно. Мінімальне та максимальне значення прояву характеристик слугуватиме для встановлення граничних меж його варіювання під час наступного моделювання господарсько-цінних показників сортів лохини високорослої.Висновки. Такі морфобіологічні характеристики сортів лохини високорослої, як сила росту рослин, листок за довжиною, листок за шириною, суцвіття за довжиною, гроно за щільністю, плід за розміром тісно пов’язані з продуктивністю рослин, виходом ягід з куща, масою ягід і врожайністю. А тому їх можна залучати до розроблення та вдосконалення моделі показників придатності лохини високорослої до поширення на території України. | Purpose.

Abstract The Microsporum canis complex consists of one zoophilic species, M. canis, and two anthropophilic species, M. audouinii and M. ferrugineum. These species are the most widespread zoonotic pathogens causing dermatophytosis in cats and humans worldwide. To clarify the evolutionary relationship between the three species and explore the potential host shift process, this study used phylogenetic analysis, population structure analysis, multispecies coalescent analyses, determination of MAT idiomorph distribution, sexual crosses, and macromorphology and physicochemical features to address the above questions. The complex of Microsporum canis, M. audouinii and M. ferrugineum comprises 12 genotypes. MAT1-1 was present only in M. canis, while the anthropophilic entities contained MAT1-2. The pseudocleistothecia were yielded by the mating behaviour of M. canis and M. audouinii. Growth rates and lipase, keratinolysis and urea hydrolytic capacities of zoophilic M. canis isolates were all higher than those of anthropophilic strains; DNase activity of M. ferrugineum exceeded that of M. canis. The optimum growth temperature was 28 °C, but 22 °C favoured the development of macroconidia. Molecular data, physicochemical properties and phenotypes suggest the adaptation of zoophilic M. canis to anthropophilic M. ferrugineum, with M. audouinii in an intermediate position.

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%).

Створити новий вихідний матеріал сої без опушення, визначити його селекційну цінність для ефективного використання продуктів переробки в годівлі тварин, що забезпечить отримання високої продуктивності останніх. Важливими господарсько-цінними ознаками при цьому є кількісні та якісні показники насіння. Відсутність опушення рослин є унікальним.Методи. Польові, спеціальні, лабораторні та математично-статистичні. Результати. Мінімальний уміст жиру в насінні – 20,88% відзначено в неопушеного сорту ‘Кобра’, у ліній № 305 та № 22 – 23,73 і 25,02% відповідно. Високим умістом жиру характеризувалися сорти ‘Алмаз’ і ‘Антрацит’ – 24,08 і 25,83%. Уміст білка в зеленій масі перспективних ліній був дуже низьким – до 16%. Уміст жиру був у межах від 2,1 до 5,3% з максимальними значеннями в ліній № 3 і № 7 – 4,67 і 5,26% відповідно. Уміст білка в насінні ‘Анаконда’ та ліній № 1 і № 9 був на рівні 36–37%, у сортів-стандартів – 29,57–35,63%. Порівняно нові лінії без опушення із сортами-стандартами та найурожайнішими сортами ‘Алмаз’ і ‘Адамос’, які занесені до Державного реєстру сортів рослин України та відповідають вимогам ефективного використання в кормовиробництві.Висновки. Відсутність опушення в рослин сої – надзвичайно рідкісне й нетипове явище. У Держреєстрі такі сорти відсутні. Понад 50 неопушених ліній культури перевищують показники господарської придатності національних стандартів і сучасних сортів. У процесі створення нових сортів з підвищеним умістом жиру в насінні доцільно використовувати неопушені лінії № 305 (23,73%) і № 22 (25,02%). Для створення кормових сортів у селекційний процес слід залучати лінії № 4, № 5, № 7, № 8, які мали в зеленій масі понад 15% протеїну. Високою харчовою цінністю характеризується лінія ‘Анаконда’ з мінімальним умістом в олії ліноленової кислоти (6,08%). Підвищений уміст олеїнової кислоти відзначено в сортів ‘Адамос’ (35,01%), ‘Алмаз’ (33,53%), ‘Аметист’ (31,39%).

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%).

Purpose. To reveal the scientific bases of forming the conveyor production of commercial products of lettuce, Lactuca sativa L., varieties in the conditions of the Western Forest-Steppe of Ukraine. Methods. Field research was conducted during 2015–2017 at the research field of the Department of Horticulture and Vegetable Growing of the Lviv National Agrarian University in accordance with the Methodology on Experimental Techniques in Vegetable and Melon Growing (2001) and Methods of Expertise of lettuce, Lactuca sativa L., varieties. Results. It is revealed that the soil and climatic conditions of the Western Forest-Steppe of Ukraine contri­bute to the optimal growth and development of all lettuce varieties of the corresponding types, as evidenced by the structure of conveyor receipt of fresh commodity products to the consumer (first decade of April – first decade of November). The shortest growing season was provided by lettuce varieties var. secalina ‘Zorepad, ‘Malakhit, ‘Dublianskyi’, which have the shortest period from seedlings to technical ripeness (21–42 days). Therefore, varieties of this variation occupy the lar­gest share in the conveyor production of commercial products, which, with early spring sowing in open ground (April 14–20), comes to the consumer in the first decade of May. Winter sowing (21.11) ensured the receipt of fresh produce in the first decade of April. Commercial products by mass of edible organs, shape of the rosette of leaves (heads, stems), color, consistency and taste qualities corresponds to the technical requirements for Lactuca sativa L. Conclusions. The selection of varieties of lettuce for the conveyor production of commercial products should be carried out taking into account the variety of the corresponding type, ripeness group, and timing of sowing. The receipt of fresh lettuce to the consumer is directly dependent on the timing of seeds sowing (early spring, late spring, summer-autumn and winter).

Полевые исследования проводили в течение 2015–2017 гг. на опытном поле кафедры садоводства и овощеводства Львовского национального аграрного университета в соответствии с Методикой исследовательского дела в овощеводстве и бахчеводстве (2001) и Методикой проведения экспертизы сортов салата посевного Lactuca sativa L. на отличимость, однородность и стабильность (2007). Результаты. Установлено, что почвенно-климатические условия Западной Лесостепи Украины способствуют оптимальному росту и развитию растений салата посевного всех разновидностей соответствующих типов о чем свидетельствует структура конвейерного поступления свежей товарной продукции к потребителю (первая декада апреля – первая декада ноября). Самый короткий период вегетации обеспечили сорта салата посевного var. secalina ‘Зорепад’, ‘Малахіт’, ‘Дублянський’, которые имеют самый короткий период от всходов до технической спелости – 21–42 суток. Сорта этой разновидности занимают наибольший удельный вес в конвейерном производстве товарной продукции, которая при ранневесенних сроках посева в открытую почву (14.04–20.04) уже в первой декаде мая поступает к потребителю. Посев под зиму (21.11) обеспечил поступление свежей продукции уже в первой декаде апреля. Товарная продукция по массе продуктовых органов, габитусе розетки листьев (головки, стеблей), окрас­ке, консистенции и вкусовым качествам соответствует техническим требованиям к товарной продукции Lactuca sativa L. Выводы. Подбор сортов салата посевного для конвейерного производства товарной продукции необходимо проводить с учетом разновидности соответствующего типа, группы спелости, сроков посева.

Розкрити наукові основи формування конвеєру виробництва товарної продукції сортів салату посівного Lactuca sativa L. в умовах Західного Лісостепу України. Методи. Польові дослідження проводили впродовж 2015–2017 рр. на дослідному полі кафедри садівництва та овочівництва Львівського національного аграрного університету відповідно до Методики дослідної справи в овочівництві та баштанництві (2001) та Методики проведення експертизи сортів салату посівного Lactuca sativa L. на відмінність, однорідність і стабільність (2007). Результати. ґрунтово-кліматичні умови Західного Лісостепу України сприяють оптимальному росту й розвитку рослин салату посівного всіх різновидів відповідних типів, про що свідчить структура конвеєрного надходження свіжої товарної продукції до споживача (перша декада квітня – перша декада листопада). Найкоротший період вегетації забезпечили сорти салату посівного var. secalina ‘Зорепад’, ‘Малахіт’, ‘Дублянський’, які мають найкоротший період від сходів до технічної стиглості – 21–42 доби. Тому сорти цієї різновидності займають найбільшу питому частку в конвеєрному виробництві товарної продукції, яка за ранньовесняних строків сівби у відкритому ґрунті (14.04–20.04) вже в першій декаді травня надходить до споживача. Сівба під зиму (21.11) забезпечила надходження свіжої продукції вже в першій декаді квітня. Товарна продукція за масою продуктових органів, габітусом розетки листків (головки, стебла), забарвленням, консистенцією та смаковими якостями відповідає технічним вимогам до товарної продукції Lactuca sativa L. Висновки. Підбір сортів салату посівного для конвеєрного виробництва товарної продукції необхідно проводити з урахуванням різновидності відповідного типу, групи стиглості, строків сівби. Надходження свіжої товарної продукції салату посівного до споживача перебуває у прямій залежності від строків сівби насіння (ранньовесняний, пізньовесняний, літньо-осінній та під зиму).
