CHARACTERISTICS OF SPRING BARLEY VARIETIES BREEDED BY THE OMSK AGRICULTURAL RESEARCH CENTER FOR PROTEIN COLLECTION

Abstract

Barley is the second grain crop in terms of importance and production volumes in most regions of Russia. However, the increased interest in this crop from the side of production in Western Siberia is constrained by the high lability of climatic factors in local conditions (frequently repeated summer droughts, a short frost-free period, heat deficiency, etc.). One of the main requirements for the variety is a high rate of “protein collection”. The purpose of the research is to characterize barley varieties bred by the Omsk Agrarian Research Center on the basis of "protein collection per unit area" in the conditions of the southern forest-steppe of the Omsk region. 13 varieties of spring barley were studied in the Omsk region from 2013 to 2018. The film varieties Sasha, Omskiy 100, Omskiy 101 and Podarok Sibiri (from +37.93 to + 64.13 kg/ha to the standard variety Omskiy 95) were characterized by an increased indicator of "protein collection", on average over the years of research. Mathematical data processing was performed. The following parameters of adaptability were studied: resistance to stress and compensatory ability, plasticity, stability, and responsiveness. The research period from 2013 to 2018 was characterized by contrasting conditions. Thus, the dry conditions of 2014 (changed to dry and cold 2015, sufficient moisture was observed in 2013 and 2018. The rank analysis of the above-mentioned adaptive capacity indicators allowed us to identify adaptive varieties for cultivation in the southern forest-steppe of the Omsk region, which can form an increased protein harvest per hectare. In order to increase the collection of barley protein in the southern forest-steppe of Western Siberia, it is recommended to cultivate filmy varieties Omskiy 99, Podarok Sibiri, Omskiy 100, Omskiy 101, Sasha (total ranks = from 33 to 47), as well as Omskiy golozerniy 1 (total ranks was 65).
