Inheritance of grain number per main spike in F1 hybrids of Hordeum vulgare l.

The results of the inheritance of grain number per main spike in F1 hybrids of winter barley under the conditions of the V.M. Remeslo Myronivka Institute of Wheat of NAAS are presented. Different types of trait inheritance were established depending on the combination of crossing. According to the type of positive overdominance (hp ≥ +1.00), 7 hybrid combinations of winter barley were selected. As genetic sources for increasing the grain productivity of plant, the variety KWS Tenor and the line Pallidum 5173 should be used as the maternal component.
