摘要
应用植物数量性状主基因+多基因混合遗传模型和经典遗传学方法对特早熟辣椒‘B9431’与‘吉林长椒’杂交组合多个世代群体始花节位进行了联合分析,结果表明:‘B9431’始花节位受1对隐性等位主基因控制,B9431×吉林长椒始花节位遗传符合1对主基因+多基因混合遗传模型。该杂交组合的B1、B2和F2群体主基因遗传率分别为83.72%、76.56%和86.63%,多基因遗传率分别为10.96%、18.58%和7.94%。
With classic genetics and the major gene plus polygene model of quantitative traits, a joint analysis of multi-generations from the cross between an extreme earliness inbred line ＇ B9431＇ and ＇ Jilin Changjiao＇ was carried out to investigate the inheritance of the node of the first flower in pepper （ Capsicum annuum L. ）. The results showed that the node of the first flower in ＇ 89431 ＇ was controlled by a recessive major gene and the inheritance of the node of the first flower fitted one major gene plus polygene model. Heritability values of the major genes of BI, B2 and F2 population were estimated as 83.72%, 76.56% and 86.63% respectively, while those polygene were 10. 96% , 18.58% and 7.94%.
