The acceleration of the process of import substitution is becoming a crucial issue in contemporary Russia and priority areas of such process are identified in plant breeding and seed production. A hot topic in the breeding of beans consists in creation of highly productive varieties with stable productivity. Field experiments were conducted at the Omsk State Agrarian University in 2014-2018 in order to evaluate the adaptation properties of prominent varieties of dry beans in terms of yielding capacity. All sorts were grown using the methods of organic farming, without application of pesticides and fertilizers, which allowed for an accurate evaluation of their biological productivity. The parameters of stability and plasticity of the genotypes under study were calculated following the methods of regression analysis (Eberhart, Russell, 1966). The associated trait of the studied feature in dry beans is mainly influenced by “environmental factors” (75%), to a lesser degree by the correlation “genotype x environment” (17%) and by “genotype” (7%). Based on the evaluation of the adaptation capacity and stability of the genotypes of common beans, samples with a high responsiveness to the improvement of cultivation conditions (Omichka, Luker’ya, Sizaya, Shokoladnitsa, Olivkovaya and Omskaya yubileinaya) and with a high genotype stability (Biichanka, Sibakovskaya-100, Rubin, Nerussa, Petukh) have been identified.
