Ruso and Leningradka varieties and F1, F2, F3 hybrids have been studied in pure and mixed planting with three areas of plant nutrition. Competitive ability was estimated by variability in plant grain content in which the varieties are not in contrast. It has been found that in the mixture of varieties Ruso is a high-competitive variety, Leningradka - a low-competitive one irrespective of planting density. In mixture of parental forms P1, P2 and F1 hybrids (1:1:2), F1 undergo beneficial effect, while P1, P2 - undesirable one. In studying the genetic analysis of quantitative characters develiped by K.Mazer, J.Jinx was applied. The nature of mutial influence of homozygous and heterozygous genotypes in model population P1+P2+2F1, theoretical one - backcrosses B1, B2, and experimental one - F2 hybrids has been studied.
