Evaluation of barley genotypes for the content of β-glucans in grain and other valuable features in Eastern Siberia

Background.The aim of the research was to identify barley germplasm accessions with minimum and maximum content β-glucans in their grain combinations other improved useful traits. Material methods.The material for analysis were 18 hulled 8 naked various ecogeographic origin from collection N.I. Vavilov AllRussian Institute Plant Genetic Resources (VIR), which grown under conditions Eastern Siberia 2016–2018. Results.Hulled yielded grains β-glucan 3.18 4.51%; ones, 5.21%. According value studied qualitative trait (3.18–3.43%), cultivars Siberian breeding identified: ‘Mayak’ (k-29622, Krasnoyarsk Territory) ‘Tarsky 3’ (k-30719, Omsk Province), plus cv. ‘AC Albright’ (k-30599, Canada); according (5.06–5.21%), Nudum 155 (k-13328, Ukraine) ‘Nudum 95’ (k-31125, Chelyabinsk Province). The highest protein (16.63–18.36%) found 155, 7566 (k-29453, Kyrgyzstan) 95’. characterized by combined high contents grain. Early maturity increased productivity shown 3’, ‘Kolchan’ (k-31039, Altai Territory), ‘Zolotnik’ (k-30845, ‘Abalak’ (Krasnoyarsk Territory, Tyumen (Canada). A significant positive relationship between weight 1000 both forms barley. Conclusion.According valuable characteristics grain, ‘Mayak’, are interest improvement fodder cultivars, while promising food.
