Abstract. The purpose of the study was to obtain productive and high-protein samples adapted to the conditions of the Primorsky Territory from the soybean gene pool. The work was performed in 2017–2019. The soil of the experimental plot was bleached meadow brown. In the collection nursery, we studied 235 samples of various ecological and geographical origins, 32% of which were from Russia, 20% from Canada, 17% from China, and no more than 5.5% from other countries. The standard was Primorskaya 13 variety. It was expedient to search for sources of resistance to diseases among species of various ecological-geographical groups: in the Asian group – to Septoria (4.6% of highly resistant samples), in the American (26.5%) and European (26.6%) groups – to Cercospora, in the European group (59.3%) – to peronosporosis. The samples Kukhanna, Doch’ Vikinga, Alena, Evgeniya (Russia); Cordoba (Australia); Opus (Canada) exceeded the standard in terms of productivity by more than 15.0%. The highest indicators of the harvest structure elements and early ripening (from 98 to 102 days) were registered in the varieties No. 073-7 and No. 54-22 (USA), YSZ-II (Hungary), Varsovie (France), Kirchest 2008 (Czechoslovakia), and Opus (Canada). We detected a direct strong relationships between the productivity trait and the number of productive nodes, beans and seeds per plant (r = 0.72–0.88). Nevesta (26.6%), Alena (24.4%), Evgeniya (24.4%), and Kitrossa (24.0%) varieties were the most promising for breeding to increase the oil content of seeds; Pi 180 529 (39.0%), Talppod-Fisk (40.4%), Kirchest 2008 (39.5%), and DSh 863 (42.3%) varieties were the most promising in terms of protein content. Primorskaya 13 (Russia), DSh 401 and DSh 863 (Canada), Cmbura 1 (Belarus) were characterized by high resistance to stress (from -0.4 to -0.9) under conditions of Primorsky Territory. Doch’ Vikinga, Alena, Evgenia, and Cordoba soybean samples were distinguished by increased genetic flexibility (more than 10.2).
Keywords: soybean (Glycine max (L.) Merr.); Primorsky Territory; germplasm; collection sample; productivity; stress resistance; flexibility.
