SUMMARY. Polymorphism of parental lines GК26, Мо17 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 testcross 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.

Key words: RILs and hybrids of maize, SSR -; analysis, genetic polymorphism, alleles combinations, frequency of alleles, combining ability, heterosis
