Comparison analysis of 24 characters involving outcrossing, floral, and rice quality traits as well as sone agrocharacters were investigated in 13 cms lines and the maintainers in indica hybrid rice. The results indicated that spikelet, stigma, style, grain shape and panicle length were longer in cms lines developed in recent years than those in cms lines developed in 1970s; stigma exsertion, outcrossing rates and rice quality were improved in newly developed cmslines. The improvemeut of the stigma exsertion and rice quality of cmslines and maintainers was also discussed in this paper.
