摘要
选用7个苦瓜自交系按双列杂交法配制21个杂交组合,分析了9个主要经济性状的配合力和遗传力。结果表明:各性状的一般配合力和特殊配合力效应均达到极显著水平。亲本P3综合性状最优,可以在育种中直接利用;组合P3×P7综合性状最优。除瓜长和始收期外,其它性状主要以非加性效应为主。
Seven inbred lines for a diallel cross were determined the combining ability and heritability. Seven parents and twenty-one F1 hybrids were evaluated for nine economic characters. Results indicated both general combining ability (GCA) and specific combining ability (SCA) were highly significant. Parental line Z-1-4 exhabited the best comprehensive characters which can be directly used in bitter melon breeding program. Z-1-4×88-3-7 had the best performance among the crosses. The type of gene action were mainly non-additive except for fruit length and day to harvest for the traits studied.
