Аннотація: Due to the climate change, constant increase in air and soil temperatures, moisture defi ciency, agricultural production requires highly adaptive varieties that would provide suffi cient yields even under adverse environmental conditions. Our breeding work is aimed at creating varieties of this type. The paper presents the results of the long-term research on assessment of soybean varieties by their adaptability under diff erent soil and climatic conditions by the yield, duration of the growing season and reproductive periods. The stability and plasticity of the researched varieties was determined using the Ebergard and Russell method. According to the research results, Artemida, Hoverla and Amethyst varieties were classifi ed as highly plastic (bi >1) by the yield and they provided the yields of 1.95, 2.2 and 2.1 t.ha-1. In terms of duration of the growing season (BBCH-10-99), Amethyst, Hoverla, Artemida and Vezha provided high adaptability. These varieties were characterized by the conservative reaction to the change in hydrothermal and soil conditions ensuring stable indicators by the duration of the growing season (BBCH-10-99), coeffi cient of pasticity (bi) was under 1. The longest fl owering-maturation period (BBCH-60-99) was observed in the following varieties: Amethyst – 69.1, Hoverla – 69.0, and Artemida – 69.1 days. The fl owering-maturation period (BBCH-60-99) was under one. By the duration of the fl owering- maturation period (BBCH-60-99), Amethyst, Hoverla, and Artemida varieties had the highest values of homeostaticity (Hom1 and Hom2), in particular, they were 32.8, 3.64 in Artemida, 30.2, 3.76 in Amethyst, 27.15 and 3.02 in Hoverla varieties.
