Sažetak
Heterosis is the increased performance of a hybrid relative to its parents. Heterosis expression depends on differences in allele frequencies between parental lines. Here we check for correlations between the genetic distance of maize parental populations, calculated using DNA-based markers and the heterosis of the hybrid populations from a half diallel mating design. All populations were evaluated in multilocation trials for a set of yield-related traits. We detected a significant correlations between genetic distances and the level of heterosis of the hybrid populations. We conclude that the genetic distance can be used as a complementary tool for maize hybrid population development.
