| Summary: | In the Rostov region there is an increase of the amount of winter wheat varieties used in the production. Out of 110 varieties used in the production in 2015, 28 varieties (or 13.3%) were new. In the sowings of winter wheat in 2015, the varieties being in the production for 6-10 years were mostly spread, including the varieties which have always been the leaders in the winter wheat sowings. Incomplete use of new varieties in the Rostov region is a reason of low grain yields. In 2015 the winter wheat yield was less on 950 thousand ton. The analysis of varietal structure of winter wheat and variety change dynamics is aimed for the development of organizational events to improve the regulation of seed market in the region on the basis of planning, forecasting and management. The increase of economic efficiency of grain production is connected with a rapid introduction of new varieties on the basis of a scientifically substantiated variety change taking into account agro ecological placement in nature-climatic zones that is impossible without well-organized seed-growing. |
