Oversaturation of the domestic market with oriented-attractive crops of foreign selection has negatively affected the production of grain – sowing rye (winter), the food value of which is noted for the significant content of proteins, carbohydrates in the grain, and in rye bread – essential amino acids (lysine, carbohydrates). vitamins (A1, B1, B2, B3, B6, PP, C). Improving the structure of domestic species production of grain crops is important for providing the population with food products and is a strategic issue of the state.

Due to dynamic changes in environmental and technological situations and in order to reduce the pressure of environmental stress factors on plant agrocenoses by the achievements of breeding, there is a constant need for systematic modification of cultivated varieties towards their greater adaptation to growing conditions, ensuring an increasing level of productivity and stability. It should be noted that the developed and recommended for cultivation varieties and hybrids of the grain direction of intensive use are characterized by high grain productivity of 8-9 t/ha, plant height of 70-100 cm, number of grains in an ear of 70-80 pcs., weight of 1000 grains of 35-45 g, protein content in grain up to 14% and complex resistance to diseases. Rye hybrids are characterized by stability, productivity, resistance to lodging and diseases. They are highly resistant to stress, have a well-developed root system, which contributes to better drought resistance and a higher tillering coefficient (up to 9 shoots).

Own varietal resources, high-quality seeds and efficient technologies for growing, storing and processing products using scientific and technological progress in the field of grain production will ensure the economic independence and self-sufficiency of each farm and the country as a whole.

Key words: sowing rye (winter), variety, weather factors, field germination of seeds, plant structure.
