IMPACT OF PARENTS GENETIC DIVERGENCE ON HETEROSIS OF F1-HYBRIDS OF SPRING TRITICALE
Molecular heterogeneity was studied in 20 spring triticale accessions by using ISSR- and RAPD-markers, which allowed the studied material to be grouped according to the degree of genetic relationship and to choose genetically distant parental pairs for crosses to obtain heterotic hybrids. Expression of heterosis of F1 triticale hybrids was studied. Evaluation of the degree of parents genetic divergence on the heterosis level of F1-hybrids revealed that increase of genetic distance values between parental components leads to higher probability of obtaining heterotic hybrids.
