The estimation of productivity of the promising lines of soybean developed by the FSBSI “ARC ‘Donskoy” The article presents the material concerning the estimation of productivity of the promising lines of soybean developed by the FSBSI “ARC ‘Donskoy”. According to the competitive variety-testing in 2015-2017 there were selected five lines that surpassed the standard variety ‘Don 21’ in seed productivity. According to the vegetation period the lines ‘L-1015’, ‘L-1018’ and ‘L-1028’ belong to the group of early maturing species, the lines ‘L-1009’ and ‘L-1010’ belong to the group of middle-maturing group. The meteorological conditions during the years of study were characterized as the years of sufficient humidity in the first half of vegetation period and the dry years in the second half of it. The statistic processing of the data has been conducted by the Dospekhov’s method of dispersion analysis. There have been estimated such parameters (according to V.V. Khangildin) as homeostasis (Hom), stress tolerance, genetic flexibility, coefficient of variability, breeding value. According to the conducted researches, assessment of lines’ productivity and parameters of their adaptability, the middle-maturing line ‘L-1009’ and the middle-early line ‘L-1015’ are the most promising ones. They possess high indexes of productivity and high parameters of adaptability (stress tolerance, genetic flexibility, homeostasis and breeding value).
