Abstract
Relevance and methods. Research work for breeding purposes was conducted in the context of ISA-branch center FNAC VIM in 2016–2018 G. G. the article presents the results of studies of gen-otypes of soft winter wheat in the collector’s nursery in 20162019 Material for the study were 14 varieties (early maturing and late maturing varieties). The purpose of the work is to study and select varieties based on the elements of plant productivity and adaptability in the conditions of the Central non-Chernozem region.
Results. According to the results of assessing the yield of winter wheat varieties in the Ryazan region, it was found that the average yield for 2016–2019 for early — maturing varieties was 5.9 t/ha, for late-maturing varieties-6.9 t/ha. On average, over the years of research, it was noted that higher yields were observed in early — maturing varietiesMironovskaya 29 (5.6 t/ha), Mironovskaya 63 (5.4 t/ha), late-maturing varieties DSV 1113 (7.3 t/ha) and MV Nador (6.4 t/ha). The coefficient of yield variation ranged from 17.3 to 23.8% for early-maturing varieties, and from 14.1 to 24.0% for late-maturing varieties. Based on the conducted research, it was found that the highest resistance to stress of early-maturing varieties was shown by Svet — Toch (-3.4) and Mironovskaya 29 (-3.8), and late-maturing varieties-Scepter (-5.7). Mironovskaya os-tistaya (-6.9), Mironovskaya 63 (-6.7), and DSV– 1113 (10.8) and Tambor (-10.7) had the lowest stress tolerance in early maturing varieties. The maximum genetic flexibility in early — maturing varieties was observed in Mironovskaya ostista and Mironovskaya 63 (5,6), and in latematuring varieties-Iststar (8,0).
