Аннотация

The evaluation results of the degree and frequency of transgression and the degree of phenotypic dominance of spring barley (Hordeum) hybrids F2 by productivity elements as a result of saturating crosses are presented. Studies were conducted in the Laboratory of Cereal Crops Breeding in Primorsky Research Institute of Agriculture from 2011 until 2017. Based on the analysis of the morphogenetic process in hybrid populations F2 of spring barley, it was established that plant productivity in multirow forms is determined by the productive tillering and the grain content in the spike. As a result, transgressive F2 hybrid combinations of spring barley were distinguished by the main elements of productivity. The highest degree of transgression (Td) was noted for productive tillering in the combination (Vostochny × Omsky 85) × Omsky 85 (120.0%), the number of grains from the main spike was observed in the combination (Primorsky 44 × Ken Pi 2) × Ken Pi 2 (29.6%), and the seed weight per plant was observed in the combination (Primorsky 89 × 03N5) × 03N5 (138.4%).
