Abstract
The nature of heterosis is discussed and selective elimination of alleles (introduced in the hybrid genotype by the parental forms) in anther culture is shown. This supports the possibility of removing viability-reducing alleles (lethal, semilethal, and less effective alleles) from the genotypes of heterotic hybrids in anther culture.
