[Predictive potential of DNA markers in heterosis breeding of maize].

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.
