Abstract
The paper deals with the results of a comparative genetic and selective characterization of F1 rye hybrids developed on the basis of G- and P-type CMS systems. It is shown that F1 G-CMS compared to F1 P-CMS hybrids are characterized by a higher ear fertility (on average by 12 %) and consequently, by increased productivity. The heterosis level of F1 G-CMS hybrids was 13.1–81.4 %, while for F1 P-CMS hybrids it was 5.7–35.0 %. Ten highly heterotic combinations were identified for the use in breeding of hybrid varieties of winter rye.
