The paper deals with the obtained results of examining the adaptive properties of winter wheat varieties cultivated in the seventh (Middle Volga) region of the Russian Federation. The following varieties were taken as the object of the current research: Bezenchukskaya 380, Nemchinovskaya 57, Scepter, Moskovskaya 56, Fotinya, Klaudia 2. This research was carried out with the aim to improve the efficiency of grain production. The chosen varieties had been studying at six levels of mineral nutrition over three years. The indicators obtained by years of research (without fertilization), characterizing the attitude of genotypes to the conditions prevailing during the growing season of crops, were considered as the influence of unregulated environmental factors. The indicators obtained during the application of fertilizers were assessed as controlled environmental factors. The adaptive properties of winter wheat varieties were assessed by indicators characterizing potential adaptability or potential productivity, resistance to stress and the intensity of reaction to favorable environmental conditions. Taking into consideration the adaptive properties of the winter wheat varieties, it was found that they are mainly potentially productive forms, but varieties differ significantly in stress resistance and reaction to favorable environmental conditions. As a result of a comprehensive assessment, conclusions were made about the advisability of using a particular variety in technologies with different levels of cultivation intensity. Firstly, the varieties such as Bezenchukskaya 380, Fotinya and Claudia 2 should be used in technologies of moderate intensity. Secondly, it would be more efficient to cultivate the varieties Nemchinovskaya 57 and Scepter using intensive technologies. Thirdly, the variety Moskovskaya 56 could be cultivated with applying both moderate and high-intensity technologies.
