Abstract
Genetic/breeding improvement of varieties is an effective method to increase yield capacity, resistance to abiotic and biotic factors of the environment and energy efficiency of crops, including barley. Knowledge of variability laws of valuable traits and their inheritance by offspring upon hybridization helps optimal selection of pairs to cross and to receive preliminary information from earlier hybrid generations about a possible final result. Targeted search for patterns of morpho-formation in hybrid populations and emergence of new biotypes enrich the applied genetics of spring barley, extend its methodological potential and allow the breeding process to be transferred to the scientific foundations of programming and forecasting. The article presents the results of studying the inheritance patterns of barley spring resistance to biotic factors and individual components of the yield structure by degrees of their phenotypic dominance in hybrid barley populations. The nature of the inheritance of the valuable trait of 1000-seed weight was found to be different, which largely depended on a crossing combination. We singled out combinations in which augmentation in expression of positive changes in subsequent hybrid generations can be expected: Talovskiy 9 / Krok, Krok / Talovskiy 9, Naran / Modern, Natali / Hatunok, and Hatunok / Natali. There is a probability to find more productive biotypes in subsequent generations of these combinations with further individual selection on a provocative background, which will make it possible to develop both resistant and productive starting material for spring barley breeding.
