Мета. Дослідити ступінь прояву послабленого стрілкування нестрілкуючих колекційних зразків часнику озимого різного еколого-географічного походження в умовах Правобережного Лісостепу України. Методи. Впродовж 2020–2022 рр. у польових умовах (м. Умань, 48°46’N, 30°14’E) вивчали дев’ять місцевих та інтродукованих зразків часнику озимого (№ 19, 27, 33, 43 і 44 з Черкаської обл., № 14 з Тернопільської обл., № 1 з Іспанії, № 16 із Франції, № 35 з Азербайджану). Під час розгляду отриманих результатів використовували загальноприйняті методи генетико-статис­тичного аналізу. Результати. Дослідженнями визначено, що у процесі утворення редукованої квітконосної стрілки маса цибулини знижувалася на 7,6–31,1% залежно від зразка, а врожайність – на 6,1–38,6%. Серед колекційних зразків за показником «маса цибулини» виділили № 16 і 44 – 57,22 і 52,24 г відповідно. Адаптивними за цією ознакою були зразки № 16, 19 і 44; інтенсивними – № 16, 27, 33 і 44, а стабільними – № 14, 19, 35 і 43. Виявлено помітну залежність між коефіцієнтом генетичної й екологічної варіації (CVG/CVA) для ознак «маса цибулини» і «врожайність», проте високої продуктивності досягнуто за умови співвідношення CVG/CVA ≥ 1. Як вихідний матеріал для подальшої селекції за ознакою «врожайність» виділено зразки: за адаптивністю й екологічною пластичністю – № 16 і 44; за стабільністю – № 19, 35 і 43 та інтенсивного типу – № 16, 27, 33 і 44, що забезпечують високу врожайність в оптимальних умовах культивування. Всі досліджувані зразки, які утворювали повітряні цибулини, характеризувалися дуже великою масою 1000 цибулин, у середньому – 1156,76 г. Максимальною масою 1000 шт. цибулин відзначилися № 16 і 27 – 1225,73 і 1638,0 г відповідно. Висновки. Отримані у Правобережному Лісостепу України дані слугуватимуть для розроблення схеми селекційних досліджень в умовах інтродукції. В результаті досліджень створено робочу колекцію вихідного матеріалу для селекції часнику класичним методом – клоновим добором.

Breeding of columnar type apple varieties has been carried out at VNIISPK since 1984. The possibility of grow-ing of columnar type apple varieties in the crown of winter hardy semi-dwarf rootstock 3-4-98 by S. N. Stepanov’s breeding is being studied in different density of planting in the orchard (3 x 1,0 m; 3 x 1,5; and 3 x 2,0 m). The inves tigation of winter hardiness, cropping power, fruit mar ketability and biochemical composition allowed releasing two varieties «Poesia» and «Priokskoye» for state trials.

Discussed problems of planetary changes of climate, through that it is necessary to revise the terms of sowing of winter crops, and also structure of sowing of agricultural cultures. The brought transpiration coefficients over of basic agricultural cultures, that must be taken into account for forming of structure of their sowing. On the example of wheat winter-annual the done attempt to be determined with priority directions in the selection of agricultural cultures.

The article researched genetic potential, morpho-biological characteristics and features of new varieties of winter wheat varieties of semi-dwarf and short-stem types. It was established that new generation of such varieties displayed improved architectonic of plants, as well as a complex of morphological and economical value chararacteristics and features, combined high genetic potential of productivity with good adopting features, and short stem with high resistance to drowning, and generated higher crop capacity compared to conventional mid-ripening varieties.
