Rezumat

On the basis of the variability of such characters as “diameter of pollen grain”, “fertility”, “sterility” were elaborated the methods of adaptive genotypes selection, evaluation of attraction capacity, differentiation of genotypes in dependence of water-holding capacity. The heritability (h2) of pollen characters “fertility” and “diameter“ were studied and F1 hybrids with high values of these characters were found (P523xB73, L1866xA285, P343xRf7, L1866xF2, L1866xCo125 Co125xL1866). It was also shown that 11 inbred lines (P343, Co125, A285, 1362, 092, XL12, MK390, Mo17, P346, 4nW23, W47) have effective genetic systems of high adaptivity.
