摘    要:以苦瓜自交系29 和惠州大顶为亲本构建6 个世代(P1、P2、F1、B1、B2、F2)群体,分别对
苦瓜单瓜种子数和苦瓜种皮颜色进行遗传分析。结果表明,苦瓜单瓜种子数的遗传符合2 对等显性主基因+
加性-显性多基因混合遗传模型(E-6 模型),由主基因和多基因共同控制,多基因显性效应较大,F1 表现
出超亲优势。苦瓜种皮颜色的黑色对棕黄色表现为1 对基因控制的显性遗传。

关 键 词:苦瓜  单瓜种子数  种皮颜色  遗传分析

Abstract:Taking bitter melon inbred line‘ 29’ and‘ Huizhoudading’ as parent,this study
developed 6 generations(P1,P2,F1,B1,B2,F2)from the cross,and analyzed the inheritance of
single fruit seed number and seed coat color,respectively. The results showed that the single fruit seed
numbers of bitter melon was controlled by 2 pairs of equi-dominant major genes plus additive-dominant
polygenes(E-6 model).The additive effects and dominant effects of the two major genes were equal.
The dominant effect of polygenes is positive and F1 expresses over-parent heterosis.Seed coat color
of bitter melon was controlled by a pair of dominant genes,black is the completely dominant traits to
brown-yellow.
Keywords:Bitter melon(Momordica charantia L    Single fruit seed number  Seed coat color
