Description
Summary:The results of estimation of combining ability of high-drought-tolerant lines of sugar corn for yield and its components are highlighted. The genotypes with high estimations of the effects of GCA on the complex of signs, the expression of which increased for the intensification of drought were highlighted. It was found out that lines KC210-3, КC416-2, RKC46, RKC18, RKC28, RKC98, RC27-5 can be donor of high drought-resistance. The samples with high donor properties of the characteristics of the structure of yield are noted. Hybrids tolerant to drought were selected, which exceeded the standard by yields of molds of technical maturation of 2.50-4.22 t/ha. The optimal combination of high yield and stability of its implementation due to increased homeostaticity of their genotypes provided them with high selective value, indicating the promising use in production.
