Abstract. Soybean is a wide spread protein and oil crop in the global agricultural production. The main challenge for active soybean growing in different regions is the response of the crop to local weather and soil conditions. The purpose of the research was to study promising soybean varieties for their adaptability parameters calculated based on the yield under the contrast conditions of Primorsky Krai. Materials and methods. Seventeen promising soybean varieties were studied according to generally accepted guidelines at the Federal Scientific Center of Agricultural Biotechnology of the Far East named after A. K. Chaika (Primorsky Krai, Russia) in 2021–2023. Scientific novelty. We evaluated promising soybean varieties for the complex of adaptability parameters and identified genotypes with high adaptability parameter values. Results. The three years of research showed that the highest yield was characteristic of soybean varieties Primorskaya 1666 (2.54 t/ha), Primorskaya 1670 (2.47 t/ha), and Primorskaya 1672 (2.68 t/ha). The method of L. A. Zhivotkov was employed to identify the most adaptable varieties – Primorskaya 1672 and Primorskaya 1666. High stress resistance was observed in three soybean varieties: Primorskaya 1673 (–2.0), Primorskaya 1668 (–7.9), and Primorskaya 4 (–9.1). Varieties Primorskaya 1669, Primorskaya 1639, Primorskaya 1668, Primorskaya 4 (the standard), and Primorskaya 1673 were found to have high plasticity (О = 3.5…16.3). Significant variance in yield was characteristic of all the soybean varieties except for Primorskaya 1673. High ecological plasticity was noted in 47.0 % of the studied soybean varieties (EPI = 1.0…1.24). The highest response coefficient to the environmental conditions was observed in Primorskaya 1667, Primorskaya 1671, Primorskaya 1596, and Primorskaya 1670 (Сr = 2.51…2.63). The conducted evaluation of the specimens for the complex of adaptability parameters allowed us to identify the soybean genotypes that were able to produce high yield under the conditions of the steppe zone of Primorsky kray. Varieties Primorskaya 1672 (the rank sum was 49), Primorskaya 1669 (52), and Primorskaya 1639 (53) was characterized by high values of the adaptability parameters.
