Japonica rice hybrids have been studied and used for 40 years (Yang 1999). For a long time, researchers have always used yield improvement as a priority goal in developing japonica hybrids. Hybrid rice has nearly become synonymous with high yield, leaving quality behind. To breed a japonica hybrid cultivar with high yield and good quality, a japonica restorer line with good quality is needed. The restorer must be genetically different from the sterile line so that good quality and high heterosis can be combined. Tianjin 1244, bred by the TRRI in 1985, is a japonica restorer line with good quality (Niu et al 1988).
