Economic and biological characteristics of promising spring barley breeding material of selection Volga region RISS

The article presents the results of the study of the breeding material of spring barley on the main economic and biological characteristics in order to identify the breeding material promising for wide use in agriculture in the region. The studies were conducted in 2017-2019 in laboratory and field conditions. It was studied 62 varieties created in the Volga region RISS. The studied varieties are characterized by the average duration of the growing season, have a high resistance to lodging, have an average height of the plant. The grain quality of the varieties studied in the competitive variety testing meets the requirements for spring barley grain. Breeding lines with high values of nature, size, low content of small grains (Submedicum 2148/00, Submedicum 2149/17) were identified. The yield of breeding lines was evaluated, a new variety of spring barley Povolzhskiy 49 was isolated and recommended for production.
