Аннотация

In the article presents results of analysis of inheritance and variability of some agronomic valuable traits in hybrids obtained with participation of cotton varieties that differ sharply in origin. Studied plants Ғ1, it was found that complete dominance of unlimited type of branching in Ғ1, effect of heterosis, complete dominance and intermediate inheritance depending on the genotype of the parental forms according to traits of precocity and weight of 1000 seeds. In the inheritance of fiber length in F2 hybrids, a wide range of variability was revealed and a markedly high variability in interspecific hybrids compared to simple hybrids. From F3Sultan x Surkhan-14 combination were selected and recommended families for breeding.
