Abstract: When creating new varieties, it is necessary to pay attention not only to high yields and the quality of the original parent forms, but also to be guided by knowledge about their reaction to changing growing environment conditions. The article presents the results of a comprehensive assessment of 15 varieties of different ecological and geographical origin. The methods of S.A. Eberhart and W.A. Russell, A.A. Rossielle and J. Hamblin, L.A. Zhivotkov, E.D. Nettevich were used in the analysis of adaptability indicators. The research was carried out in the northwestern part of the Ryazan region in the fields of ISA – a branch of the Federal State Budgetary Educational Institution FNAC VIM in 2019–2023, of which two years were unfavorable – the index of environmental conditions (Ij) –2,54 – –1,87, three years favorable Ij was 0,84–2,24. It was found that, on average, over 5 years of research, the highest yield potential was possessed by the varieties of winter wheat Danaya – 5,79 t/ha, Isktar – 6,36 t/ha, Nebokrat and Slavna – 5,81 t/ha and 6,09 t/ha, which is higher than the average annual indicator by experience by 11,1%, 22,1%, 11,5% and 16,9%, respectively. The group of the most plastic varieties includes: Danaya and Lavina (Russia), Nebokrat and Slavna (Ukraine), Isztar (Germany). High responsiveness to improving environmental conditions was noted in winter wheat varieties Moskovskaya 39 (Russia) – 1,22, Fantasia (Belarus) – 1,23, Saturnus and Tambor (Germany) – 1,17 and 1,41, respectively. According to the complex of adaptive properties, the Isztar (Germany) and Nebokrat (Ukraine) varieties were distinguished as genetically flexible ((Ymin + Ymax)/2 from 5,56 to 6,26), with a high level of stability (PUSS from 103,28% to 113,12%), good adaptability to environmental conditions (KA – 1,15% and 1,26%, respectively) and resistance to stress ((Ymin – Ymax) from –4,23 to –4,68). The research results can be used in practical breeding.
