Abstract
Agroclimatic features of the regions of barley cultivation necessitate the creation and cultivation of cultivars characterized by adaptability to local bioand abiofactors. Such cultivars are able to form a stable high-quality crop regardless of the conditions prevailing during the growing season. The developing of potentially high-yielding cultivars is a priority task of barley breeding in the West Siberian region. Two-row barley is characterized by grain equalization, reduced husk content and increased extractive content, compared to sixrow barley. The aim of the study was to characterize the new promising cultivars of barley (two-row covered group) selected in Omsk Agrarian Scientific Center. The research was conducted in the southern forest-steppe of Western Siberia in 2012-2019. 8 cultivars of coverd two-row barley selected in Omsk Agrarian Scientific Center were studied. There are new promising cultivars among them: ‘Omskiy 100’ (included in the Russian State Register in 2019) and ‘Omskiy 101’ (sent to the State Registration Service in 2018). The standard cultivar was ‘Omskiy 95’ (2007). The biochemical parameters of grain were determined: protein content, crude fat, starch, husk content. Barley selection from 2000 to 2019 focused on the developing of drought-resistant cultivars, which formed increased productivity and quality of grain in dry and arid periods of vegetation in conditions of optimal moistening. New promising cultivars - ‘Omskiy 100’ and ‘Omskiy 101’ were characterized by the formation of increased indicators of grain quality and productivity in vegetation periods that were contrasting in climatic characteristics. Due to increased yield and grain quality, cv. ‘Omskiy100’ had increased protein (+57.91 kg/ha), starch (+0.3 t/ha) and fat (+11.7 kg/ha) harvest compared to the standard. Cv. ‘Omskiy 101’ increased protein harvest by 84.9 kg/ha in comparison to the standard.
