Evaluation of technological and cereal qualities of grains of zoned barley varieties grown in Subtaiga-taiga zone of the Irkutsk region

Abstract

Abstract Among the varieties of barley (Hordeum sativum), barley nutans varieties have the best qualities for food processing according to state standards (GOST) 28672-90. The paper presents the results of cultivation and a comprehensive assessment of technological parameters of grain of zoned barley varieties: Acha, Abalak and Biome obtained in the conditions of the subtaiga-taiga zone of the Irkutsk region. Barley was grown according to the steam predecessor on gray forest soil with a high level of fertility according to the methodology of the state network for testing varieties in the Nizhneudinsky state site of variety testing. Grain quality assessment was carried out according to generally accepted methods in accredited laboratories. It is shown that grain quality is subject to dynamics due to changes in meteorological conditions during the cultivation of barley. In terms of nature, all varieties meet the requirements of GOST 28672-90. Grain Biome is characterized by a higher mass of 1000 grains (more than 50 g), which subsequently affects its cereal qualities. The quality of cereals in all varieties is rated as “excellent”. In terms of uniformity, cereal yield and protein content in grain, the best among the studied varieties was Biome. Thus, the cereal quality of the grain obtained in the region meets the requirements of the processing industry and is determined by the variety.
