摘　　要：本文采用B.C.Sood(1978)介绍的水稻香味快速测定法对水稻不育系宜香1A的香味遗传进行了研究,结果宜香1A的香味遗传由1对隐性主基因控制。用4个不育系与5个恢复系组成4×5不完全双列杂交作配合力分析,分析结果为宜香1A一般配合力效应值为0.375616,II-32A的配和力效应值为0.168767,汕A的配和力效应值为-0.20795,对它们配和力效应值差异作显著性测验的结果是宜香1A一般配合力极显著优于II-32A和汕A。This paper studied on scent inheritance of cytoplasmic male sterile line Yixiangl A in rice. The method is the rapid technique for scent detemination revealed by B. C. Sood（1978）. The result showed that Yixiangl A＇ s scent inheritance is controlled by a pair of single recessive main gene of scent. YixianglA＇ s yield combination ability analysis was made by incoplete diallel with 4 CMS lines and 5 restorer lines. It is the result that Yixi- anglA＇s general combination ability effect value is 0.375616. Yet II-32A and San A＇s general combination ability effect value is 0. 168767 and 0.20795 seperately.So Yi：danglA＇s general combination ability is prior to Ⅱ-32A and San A＇s after checking of difference significance.
