The purpose of the research was the agrobiological assessment of new varieties of winter wheat depending on different methods of sowing in the South-Western part of the Central black earth region of Russia. The optimal row spacing for the studied varieties, providing the highest rates of growth, development and productivity, is determined. It was found that the maximum germination of wheat seeds – 85.8%, was in the May Jubilee variety with an ordinary method of sowing, which is 3.7% higher than these varieties-standard. A similar pattern is identified in the wide-row sowing method between rows of 30 cm germination varieties may anniversary in this variant were higher by 3.1% compared to Odessa 267.
The analysis of the structure of the crop (weight of 1000 grains and grain yield) revealed a change in its structural elements under the influence of different row spacing. May Jubilee variety on the complex of the studied parameters had an advantage over the standard variety, including the yield, which was about 3.82–4.11 t/ha of grain. Thus, the new varieties May Jubilee and Belgorod 16, having the greatest adaptability to the growing conditions showed the potential of productivity most fully. The best way of sowing new varieties is a wide-row with rows of 30 cm on the options with which the increase in grain yield depending on the variety was 0.32–0.39 t/ha.Keywords: grain quality indicators, sowing method, the growing season, variety, winter wheat, yield
