[目的]分析中国与南亚水稻恢复系资源产量及其构成要素的一般配合力差异,为引进与利用南亚资源提供参考。[方法]按照NCⅡ设计,将来自中国和印度等国的37份恢复系材料分别与46A、泸98A和德香074杂交,获得111份杂交种作为试验材料。在四川泸州和德阳两个环境下,分析8个产量性状的配合力。[结果]在两种环境下,8个性状在组合间、恢复系间、不育系间、不育系×恢复系间均达到显著或极显著差异水平,说明各组合间基因效应确实存在着遗传差异;亲本一般配合力方差均大于特殊配合力方差,表明这些性状受到基因加性效应的影响。恢复系对杂种一代性状的影响大于不育系。来自印度和孟加拉的9份材料的有效穗一般配合力在两个环境中都排在前15位。[结论]中国与南亚恢复资源产量性状配合力有一定的差异,印度和孟加拉资源有效穗配合力好于中国资源,中国资源其他性状一般配合力优于南亚来源材料。 [Objective] The research aimed to analyze the differences of general combining ability between the yield and its components of rice restorer lines in China and South Asia, and provide reference for the introduction and utilization of South Asia resources. [Method] According to NC Ⅱ design, 37 restorer lines from China, India and other countries were crossed with 46A, Lu 98A and Dexiang 074, respectively, and 111 hybrids were obtained as test materials. Under the environment of Luzhou and Deyang in Sichuan, the combining ability of 8 yield traits was analyzed. [Result] Under the two conditions, the eight traits all reached significant or extremely significant differences among the combinations, between restorer lines, between male sterile lines and sterile lines × restorer lines, indicating that the genetic effects among the combinations did exist Genetic differences; The variance of general combining ability of parents was greater than that of special combining ability, which indicated that these traits were affected by gene additive effect. The restorer lines have more influence on the hybrid generation traits than the CMS lines. The effective spike general combining power of 9 materials from India and Bangladesh ranked in the top 15 in both environments. [Conclusion] There was a certain difference between the combining ability of the yield traits of recovery resources in China and South Asia. The effective spike co-efficient of resources of India and Bangladesh was better than that of China, and the general combining ability of other traits of Chinese resources was superior to that of South Asian origin.
