[Allele structure of polymorphic loci of maize lines and hybrids and its correlation with heterosis level].

Polymorphism of parental lines GK26, Mo17 and lines-testers Od221MB, Od308MB, and Od329 was analyzed by SSR-PCR and genotyping of recombinant inbred lines (RIL) from populations F4, F6 was carried out. Ten microsatellite loci allele combinations of parental lines, lines-testers and the best test cross hybrids were established and their molecular-genetic formulas were derived. The microsatellites allele structure of the best for combining ability lines and high-yield hybrids was investigated.
