Abstract

The article presents evaluation of degree and frequency of transgression, degree of phenotypic dominance of F hybrids of spring 2 barley according to the productivity elements in the result of saturating crosses. The study was conducted in the laboratory of cereal crops breeding in FSBSI "Primorsky scientific research Institute of agriculture" from 2011 till 2017. Based on the analysis of the formative process in hybrid populations F of spring barley, it was defined that productivity of plants of multi-row forms effects upon 2 productive tillering and ear grain content. As a result of the research there were defined transgressive F hybrid combinations of spring barley according to the main elements of productivity. The greatest degree of transgression(Tc) was observed according to theproductive bushing in combination (Vostochny x Omskiy85) x Omskiy x 85 – 120,0%, according to the seeds number from the main spike in combination (Primorskiy 44x Ken Pi 2) x Ken Pi 2 – 29,6 % and the seeds weight per plant (Primorskiy 89 x 03N5) x 03N5 – 138,4%.
