玉米穗部产量性状配合力和遗传参数分析

Analysis of Combining Ability and Heredity Parametric of Corn Yield Character

以来自不同杂种优势群的10个自交系为供试材料,按Griffing双列杂交方法Ⅳ组配成45个杂交组合。对穗部产量性状进行配合力、遗传参数分析,并对亲本和组合进行了评价,筛选出了优良亲本和优势组合。

According to Griffing Ⅳ methods, the study synthesized 45 cross came from 10 maize inbred lines belonged to different heterosis groups. To choose elite parents and advantage cross, yield traits on ear were performed analysis of combining ability and genetic parameter, parents and cross were evaluated
