This article presents the results of a comparative study on the formation of agrocenoses in winter wheat varieties bred under the conditions of southern Russia and the Middle Volga region. It is shown that varieties of dif-ferent breeding origin coincide with the period of active vegetation by the dura-tion of plant development phases. Therefore, the vegetation period of varieties in relation to local natural and climatic conditions does not limit the formation of productive agrocenosis. The comparative evaluation of varieties of the southern selection and varieties of the Middle Volga region has shown that in most cases, regardless of the conditions of breeding origin, the varieties have high winter hardiness, safety and survivability of plants, which allows them to form a productive agrocenosis. It was found that the varieties bred in southern Russia are characterized by high potential bushiness, which is a characteristic feature of the variety. The varieties of the Middle Volga region, on the other hand, have an unclear tillering characteristic. The varieties are mainly charac-terized as forms with moderate bushiness potential. At the same time, under the conditions of the Middle Volga region, it is also possible to produce varie-ties with a high potential bushiness. These varieties include, for example, Vyu-ga and Vertikal. From the results obtained, it can be concluded that it is advis-able to use foreign varieties of southern selection under local soil and climatic conditions.
Keywords: vegetation period, winter hardiness, plant safety and surviv-al, productive bushiness.
