named after Bohdan Khmelnytsky Наведено результати трирічних досліджень з вивчення сортозразків квасолі звичайної (Phaseolus vulgaris L.) щодо екологічної пластичності, стабільності і стійкості до хвороб в умовах центральної підзони Правобережного Лісостепу. Виділено сортозразки квасолі, що проявили високу стійкість до фузаріозу, реакція яких на надлишкове зволоження на початкових та дію високих температур на завершальних фазах росту й розвитку була мінімальною-UD0303600 і UD0303528. Найвищу стійкість до бактеріозу забезпечили сортозразки-UD0303601, UD0303526, UD0303543 і UD0303557. Серед них UD0303601, UD0303526 були стійкішими за несприятливих умов вирощування. Найвищу стійкість до бактеріального в'янення в тому числі і за несприятливих умов вирощування забезпечили сортозразки-UD0300414, UD0301063 і UD0303543. За стійкістю до вірусної мозаїки виділили сортозразки: UD0303543, UD0303557 і UD0303610, вони були кращими за всіх умов вирощування. Ключові слова: квасоля звичайна, сортозразок, екологічна пластичність, стабільність; стійкість до хвороб. Introduction. Beans take the second place in the world among the legume crops, but in Ukraine its cultivated areas are small and mostly concentrated in the private sector. One of the main reasons is the lack of varieties adapted to various soil and climatic conditions that are characterized by unstable crop yield and lack of technological ability to mechanized harvesting. In solving the problem of creating competitive varieties, a detailed study and adaptation to the specific conditions of the source material is relevant. To create a new source material, which would be characterized by a complex of valuable economic and biological features, grain yield and adaptability, it is necessary to conduct a detailed assessment of the collection varieties at the microplots in the primary stages of the breeding process. Analysis of recent research and publications. Plant growing conditions are important in forming their resistance to various diseases. In nature, the pathogens
Agrobiological assessment of soybean varieties Glycine max var. Shirofumi on a complex of economically valuable traits for introduction in the conditions of the Forest-Steppe of Ukraine. Selection of promising breeding forms based on morpho-biological and physiological-biochemical characteristics. Methods. Field, laboratory, statistical, computational and analytical. The studies were carried out in the conditions of the educational and production department of Uman National University of Horticulture during 2020-2021, using collection varieties of different ecological and geographical origin (Ukraine, Belarus, Sweden, Japan and Russia). The cultivars were assessed according to the following parameters: plant height, leaf area, net productivity of photosynthesis and indices of individual productivity (weight of beans per plant, number of seeds in a bean, etc.), productivity of green beans and biologically mature seeds and, accordingly, quality indicators of production (dry matter, sugar and protein content). The counts were carried out in the phase of the technical ripeness of the beans. Results. The variability of the "plant height" trait of the studied varieties had an average variation -the coefficient of variation was 22%. The results showed that the standard cultivar 'Romatnyka' and the collection cultivars 'Karikachi' and 'Astra' belong to the semi-determinant type of growth (97-109 cm), cultivar 'Fiskeby V', 'L 380-2-13', 'Fiskeby V-E5', 'SibNIISOKh 6', 'Sac', 'Vesta' belong to the determinant type of growth. According to the number of seeds in the pod, the studied varieties were clearly divided into two groups: with two-seeded beans (varieties 'Karikachi', 'Astra', 'L 380-2-13') and three-seeded beans [varieties 'Romatnyka' (standard), 'Fiskeby V', 'Vesta', 'SibNIISOX 6', 'Sac', 'Fiskeby V-E5']. The maximum yield of edamame beans was produced by varieties 'L 380-2-13' (17.3 t/ha), 'Vesta' (18.8 t/ha), 'Sac' (19.6 t/ha), 'Fiskeby V' (21.4 t/ha), 'Fiskeby V-E5' (22.4 t/ha). A significant differentiation of soybean varieties in the biochemical composition of immature beans was revealed. The dry matter content was 22.70-31.70%. The share of protein in edamame green beans was 28.2-38.6%, in biologically mature seeds its share increased to 36.1-42.8%. Among soluble sugars, the highest concentration was noted for sucrose -7.70-9.38 mg/100 g in dry seeds, what in average amounted to 81.6-86.2% of all sugars. The presented results provide a comprehensive assessment of breeding work on soybean varieties with a low content of oligosaccharides. Conclusions. Evaluation of collection varieties of vegetable soybeans by the variability of morphological traits and productivity made it possible to distinguish 'Sac' variety by a complex of valuable traits for creation of new varieties of vegetable soybeans adapted to the conditions of the Forest-Steppe of Ukraine.
