摘要: 选用陆地棉无限果枝类型和有限果枝类型品系进行杂交,构建两个F2分离群体,利用主基因+多基因遗传模型的P1、P2、F1、F2四世代联合分析法对陆地棉果枝类型的遗传模型进行分析,结果表明,两个杂交组合分析结果一致,果枝类型均为E-0模型,即两对加性-显性-上位性主基因+多基因遗传模型,最优遗传模型的两个主基因均以加性效应为主,果枝类型性状的大纯合主基因对次大主基因存在显性上位作用。果枝类型与产量性状间的相关性分析表明,无限果枝类型个体与铃重、籽棉、皮棉产量及生育期呈显著正相关。

关键词: 陆地棉, 果枝类型, 主基因+多基因混合遗传模型, 遗传分析

Abstract: Two F2 segregate population were constructed by unbounded fruit branch type and bounded fruit branch type.The method of joint analyses of multiple generations with P1,P2,F1 and F2 of major gene plus polygene mixed inheritance model was used to analyze the genetics of cotton fruit branch type.The results showed that cotton fruit branch type was controlled by two major gene with additive-dominance-epistasis effects plus polygenes and with accordance in two populations.Two major genes have additive effect mainly and there was epistatic dominance effects between two major genes.The correlation analysis indicated that unbounded branch plant was positive correlation with boll weight,seed cotton yield,fiber yield and growth period.

Key words: Upland cotton, Fruit branch type, Mixed major genes plus polygene inheritance model, Genetic analysis
