摘要
本文介绍了产地差异较大的棉花品种参与杂交获得的一些农艺有价性状的遗传和变异分析结果。以植物Ғ1为研究对象，发现Ғ1存在无限型分枝的完全显性、杂种优势效应、根据亲本型基因型的完全显性和中间遗传(根据早熟和千粒重性状)。在纤维长度遗传方面，F2杂交种表现出较大的变异性，种间杂交种的变异性明显高于单纯杂交种。从F3Sultan x Surkhan-14组合中选择推荐家系进行育种。
INHERITANCE AND FORMATION OF SOME ECONOMICALLY VALUABLE TRAITS IN COTTON HYBRIDS F1, F2 AND F3
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.
