摘要
采用多点的不完全双列杂交设计，在AMMI模型分析稳定性的基础上，进一步分析了稳产性的配合力及其与丰产性的关系，结果表明杂交稻丰产性及其亲本的配合力均与试点存在交互作用，材料间稳定性差异较大；稳产性与丰产性间相关不显著；杂交稻F1的稳产性同时受双亲一般配合力和特殊配合力的作用，且以基因加性效应为主，但均不可忽视。选育稳产性好的杂交稻组合，至少应有一个稳产性配合力高的亲本。
Based on the data from incomplete diallel crossing at 4 different experiment sites, the combining ability for grain yield stability in hybrid rice and relationships between grain yield and its stability were analysed by AMMI model. There were interaction effects between sites and both grain yields of combinations and their combining ability of parents. The relationships between grain yields of combinations or combining ability of parents and its stability were not significant at 5 % or 1 % level. The grain yield stability in hybrid rice was controlled by general combining ability (GCA) and special combining ability (SCA) of parents, and GCA was more important than SCA.Breeding hybrid rice combination with high stability of grain yield needs at least one parent with higher GCA for stability.
