Evaluation of promising lines of spring barley in the conditions of the Northern Trans-Urals

Abstract

This article presents data on the results of a long-term study of promising lines of spring barley in the Tyumen region. The experiment was conducted in 2019-2022 at the experimental field of SRIA (Russia) using generally accepted methods of analysis and standard techniques. 56 samples were evaluated, including 36 of them evaluated by two precursors (peas and spring grains). The analysis of the data showed a decrease in yield according to the predecessor – cereals, without fertilizers by 14.8%. The growing conditions significantly influenced the grain nature, hoodness, protein and fat content (the share of influence was 85.8, 60.9, 55.5 and 72.7%, respectively). The weight of 1000 grains largely depended on varietal characteristics (the share of influence was 63.1%). The formation of starch was significantly influenced by the interaction of genotype and environment (the share of influence was 71.6%, respectively). As a result of the breeding material evaluation, 17 promising samples of spring barley, including four huskless ones, were identified.
