Use of sources of resistance to smut in the breeding of spring barley

Abstract

The paper aims to create and study the complex of traits of the multi-row forage barley variety Krasnoyarsky 91. The selection sample K-8-19 and the Acha variety were used as parent forms. The variety has been included in the state register of breeding achievements since 2017 in the East Siberian (11) region. Recommended for cultivation in the Krasnoyarsk Territory, the Republic of Khakassia, Tyva, Buryatia. Multirow, a type of pallidum. The duration of the growing season is medium-late. On average, over three years (2012-2014) in the competitive test, the grain yield of the variety ranged from 26.3 to 40.5 c/ha, with an average yield of 32.1 c/ha. The advantage over the Acha variety was 4.0 c/ha, and over the Sobolek variety 6.3 c/ha. The variety has a high yield of green mass. When harvesting for green fodder, the advantage in terms of green mass yield in terms of dry matter ranged from 0.6 to 20 c/ha. Krasnoyarsk 91 is resistant to fungal diseases. The variety is recommended for use for feed purposes.
