The economic value of winter barley and their use in spring breeding in the Tyumen region

The potential of barley in terms of yield and protein content in grain has been realized in the Tyumen region, as well as in Siberia as a whole, by 30-40%. In solving this problem, the variety is of particular importance. To create barley varieties well adapted to the conditions of the region, valuable source material is needed, as which winter barley varieties are of great scientific interest. In 2017-2023, winter barley varieties were studied in the experimental field of the State Agrarian University of the Northern Urals. It was found that during winter sowing (April 10-15), winter barley varieties in the second half of April give friendly shoots, then grow normally, develop and form a grain yield of 5-6 t/ha with a protein content of 11.0-11.9%. Barley varieties are resistant to diseases and lodging. When crossing spring barley varieties with winter crops, hybrids were obtained, from which the parent plants were selected in the second generation, successfully combining the productivity of the ear with the protein content of the grain and other valuable characteristics. The obtained source material is studied according to the scheme of the breeding process.
