The main yield and rice quality traits of 9 two-line hybrid rices in Sichuan were analyzed. The results showed that Guangzhan 63 S /R9348 had the highest yield,and minimum yield in 33 S / 9311. Y58 S lines had longer panicles,more filled grains and higher seed setting,which were major reasons to improve yield for Y58 S lines as female. Guangzhan 63 S had the most effective panicles,and there was not obvious advantage for major yield traits in 33 S lines. Y58 S / R9348 had good quality in level 3. Generally speaking,the main quality indicators of two-line hybrid rice were better than that of CK.
