The article presents the results of a comprehensive assessment of the adaptive properties of spring vetch, carried out in 2021 - 2023 on the territory of the Orel region. The purpose of this work was to identify varieties of spring vetch most adapted to the contrasting conditions of the southeast of the Orel region. The objects of research were domestic varieties of spring common vetch bred by the FSBSI Federal Scientific Center of Legumes and Groat Crops - Kshen, Assorti, Livenka, Ksenia, and the FSBSI Federal Research Center "Nemchinovka" - Mega and Marinka. The following indicators were taken into account: resistance to stress (Ymin-Ymax), compensatory ability (Ymin+Ymax)/2, adaptability coefficient (KA), coefficient of variation (V), homeostaticity (Hom), breeding value (Sc), regression coefficient (bi); adaptability coefficient (st2). The equal significance of the influence of “environmental effects” on the yield of the studied varieties was revealed. It has been established that the spring vetch variety Ksenia has the most adaptive properties when cultivated in the south-east of the Orel region, and the Mega variety was less adaptive in the climatic conditions studied.
