The influence of weather conditions on dynamics of accumulation of dry matter in grain of winter wheat varieties in conditions of forest-steppe of Samara region

The article presents the results of research for 2016-2017 on the influence of environmental conditions on the dynamics of dry matter accumulation in the grain of winter wheat varieties in the Samara region. Varieties created in the laboratory of breeding and seed production of winter wheat are characterized by a rapid rate of accumulation of dry matter. They are adapted to the formation of high-grade grain in the unstable arid climate of the middle Volga region. As a result of the research, the best varieties for the accumulation of dry matter in grain were: Povolzhskaya 86, Povolzhskaya niva, Povolzhskaya nov’, Eritrospermum 3730 and Eritrospermum 3627.
