Abstract The results of the study of breeding values of self-pollinated lines of maize, different by genetic basis are presented. For a more complete and detailed study of the inheritance of the starting material signs inbred-family of different generations were seeded, which determined the degree of depression. This fact gave the possibility to highlight the valuable line, characterized by a high level of manifestation of a number of signs. The purpose of our research was to define the efficiency lines of maize, different by their genetic basis and disease and pests resistance. In hetherosis selection the choice of parental couples for crossing is very important. The maximum hetherosis effect is reached only by hybridization of specially chosen lines. One of the biggest source of increasing corn seed production is maintenance and providing highly productive hybrids with stable output by changeable environmental conditions, stable to laying out, diseases and pests, intensive vaporizing of seeds, those which completely correspond to demands of industrial growing and harvesting.
