The source material estimation of early-maturing group soybeans by adaptability parameters

The article presents the results of 2018—2020 study 22 early-maturing group soybeans samples collection nursery; those are various ecological-geographical origin according to adaptability parameters, plasticity and stability in conditions south Amur region, analysis yield variability was carried out. research out on experimental field laboratory selection genetics FSBSI FSC All-Russian Scientific Recearch Center soybean, Sadovoye village, Tambov region. average varietal soybean seeds years amounted 2.37 t/ha. Based agro-ecological assessment samples, adaptive, plastic stable have been identified, which an insignificant variation indicator yield: Heihe 25 (V=3.23%; Ка=1.14; bi=1.00; Si2=0.03), Hei 06–1625 (V=4.69%; Ка=1.06; bi=1.29; Si2=0.01), 05–1031 (V=3.74%; Ка=1.03; bi=1.60; Si2=0.01) McCall (V=2.34%; bi=1.03; Si2=0.01). These genotypes practical interest as initial parent forms for
