Development of breeding material and drought-resistant Hordeum vulgare varieties

Hybridization between different genotypes of Hordeum vulgare with different vegetative period due to their maturity was carried out in the study. Fertility of flowers during pollination was 21.7-63.1%. Vegetation period of parental forms was 190-214 days. Full dominance was observed in 18.75% and partial dominance in 25.4% of F1 Hordeum vulgare hybrids. 56.25% took an intermediate position. Hybrids of the F2 generation had a wide spectrum of fragmentation. In fast-growing hybrids with a relatively short vegetation period, the corresponding indicator was 3-12 days less than in both parental forms. This allowed it to be selected for practical use in selection lines with a relatively short vegetation period.
