ABSTRACT
PCR-analysis of maize inbred lines has been carried out. Genetic distances between the lines have been calculated, allelic composition and heterosis level of F-hybrids have been determined. Heterosis level of hybrid seed yield rised according to increasing of genetic distances between initial lines. Correlation of allelic composition of inbred line microsatellite loci and heterosis level of the respective hybrids has been revealed.

The results of SSRP-analysis of molecular-genetic polymorphism in maize inbred lines and simple hybrids are presented. Character of inheritance of amplicons obtained by SSR-PCR-method was investigated. Test-system for determination of hybridity of simple maize hybrids was proposed, which showed high probability of exclusion of unrelative male forms.
