Abstract: There were identified soybean varieties that combine high genotype potential and stable yields being the best ones under a set of adverse conditions as well as a positive response to the improvement of growing conditions. The varieties were differentiated by the level of ecological potential in accordance with their response to the growing conditions in different soil and climatic conditions of research. Evaluation and differentiation by the plasticity and stability allowed us to identify environmentally adapted genotypes by the yield, length of the growing season, seed quality. Varieties Adamos, Alexandrite and Aquamarine appeared to have high plasticity by the yield, weight of 1000 seeds, growing season and high quality of seeds. They responded well to the improvement of growing conditions and, by the yield and quality of seeds, provided high stability of the manifestation of traits in various hydrothermal and edaphic conditions of Ukraine. Varieties Almaz, Anthracite and Avanturine appeared to be more conservative in their response to environmental changes having high stability.
Soybean varieties of Poltava breeding are highly adaptive and they can confidently provide efficient soybean production in different soil and climatic conditions of Ukraine.
