摘 要 ：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。利用来自中国和印度等国的37份恢复系材料，按照NCⅡ设计，分别与冈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。结果表明：（1）8个性状在两个环境下，一般配合力和特殊配合力方差达到显著或极显著水平，一般配合力方差均大于特殊配合力方差，表明这些性状基因的加性效应占主导地位。（2）分析的8个性状，杂种一代性状受恢复系的影响大于不育系。（3）印度和孟家拉材料有效穗一般配合力好于中国资源，其他性状一般配合力，中国资源优于南亚来源材料。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较好，中国恢复系资源其他性状上较好。

Abstract:For providing a reference on introduction and use of South Asia rice restorer lines resources，the combining ability analysis of yield trait was studied in rice restorer lines between China and South Asia by a NCⅡ mating design. 37 restorer lines from China and South Asia were used as male parents, and 3 CMS line,Gang46A,Lu98A,De-xiang074A were used as female parents, 111 hybrids were gained. The hybrids was planted in Lu-zhou city and De-yang city of Sichuan province in China respectively, and 8 yield traits was investigated and analyzed. The results shows: (1) Both general combining ability（GCA） and specific combining ability（SCA）were significant at 5% or 1% levels on 8 yield traits, and the additive effects were more important than non-additive effects. (2) The Yield traits were greatly influenced by restorer lines than by fmale sterile lines.(3) There are different between China and south Asia restorer lines on yield trait GCA, and India and Bengal restorer lines has a better GCA on tiller number than Chinese resource，Chinese rice restorer lines is better than South Asia resource on other yield traits GCA..
