Lines and hybrids of maize with higher frequency of matroclinal haploid production were revealed. It was shown that the degree of ear grainness after pollination by marker genotype inducing matroclinal haploids fell down on more than 50 %. It was established that in the inheritance of the character frequency of matroclinal haploidy the leading role belonged to additive effects. Genetic control of degree of ear grainness is founded on the dominance of low grainness. Recessive alleles are responsible for the increasing of both characters. The studied lines were characterized concerning to the ratio and the direction of action of dominant and recessive alleles.
