通过双列杂交试验分析了水稻不育系蓉18A的配合力,结果表明,蓉18A产量一般配合力与宜香1A相当,显著高于中9A和与金23A,穗大粒多是蓉18A产量一般配合力较高的主要原因;主要米质性状一般配合力与宜香1A相当,优于中9A和金23A。蓉18A产量和米质性状一般配合力均较高,是选育优质、高产杂交水稻的优良亲本。 The results showed that the general combining ability of Rong 18A was similar to that of Yixiang 1A, significantly higher than that of Zhong 9A and Jin 23A, and the yield of Rong 18A was mostly The main reason for the higher co-operation force; The main co-performance of the main quality traits with Yixiang 1A, better than in 9A and 23A. The yield and quality traits of Rong 18A were higher than those of the other two cultivars. It was an excellent parent for breeding high quality and high yielding hybrid rice.
