This paper presents the results of an experiment on a soybean collection under the conditions of Primorsky Kray with a focus on economically important traits and prospects for the use in a breeding program. Based on the evaluation results, promising soybean specimens were selected for the following parameters: time to maturity, yield, seed composition, and resistance to diseases. The selected specimens were characterized by early maturity (varieties Ariya, Kruzhevnitsa, SK Agra (Russia), K0152, Alisa, Torlitsa, Romantika (Ukraine), Adsoi (Germany), ESG 141, ESG 152 (France), and Varsovie (Poland)); high yield (exceeded the standard variety Primorskaya 4 by 100,4%) (varieties Briz (Russia) and ES Pallador (France)); large seeds (up to 204 g) (varieties Primorskaya 1259, Briz, SK Viola (Russia), and D402-NN51 (China). Varieties Briz (42.3 %), ES Mentor (42.0 %), and SVKh 14 TOS 10 (41.8 %) had the highest and most stable content of proteins. Resistance to Septoria leaf spot was observed in varieties Briz, Vityaz’ 50, Primorskaya 1259 (Russia), and Khefeng 25 (China). All varieties showed resistance to downy mildew and Cercospora leaf spot. The established correlation evidences that Septoria leaf spot has an adverse effect on the formation and development of the reproductive organs of soybean plants.
