Abstract
The article presents the material on the assessment of productivity of released varieties of winter wheat in the conditions of the Central Chernozem region.On the territory of Russia more than half of the sown area of grain crops is occupied by wheat, 70% of which is the area of winter crops. In advanced farms there is a high culture of agriculture (crop rotation, fertilization, soil treatment, etc.). However, the yield of winter wheat throughout the country is still insufficient and does not reach the maximum potential of the crop. One of the reasons for this is the lack of a scientifically based varietal technology for growing this crop in relation to soil-climatic and regional zones.
