Thirty hybrids and their 13 parents (3 male sterile lines and 10 restorer lines) were studied on the combining ability and heterosis for rice quality. The results showed that:(i) Most quality traits of rice hybrids had the measurements between their parents and no significant heterosis except the grain weight showed the over-high-parent heterosis, grain chalkiness had positive average heterosis. (ii) Male sterile lines and restorer lines had a great effect on the hybrid rice quality. Grain length, grain width and amylose content heavily depended on the male sterile lines, but head rice rate, grain weight, chalky grain rate, grain chalkiness and alkali spreading value greatly depended on the restorer lines than the male sterile lines. (iii) Parents Guangzhan 63-4S, Yangdao 6, R527 and Zhenhui 084 had good GCA and SCA,and can be widely used for new quality hybrids breeding. Teqing and Yanghui 559 had the low GCA and SCA and less significance for rice quality breeding.
