Abstract: In order to learn characteristics and the role of rice waxy lines in hybrid rice breeding, agronomic traits, grain quality, resistance and restoring force has been identified on waxy rice with early maturity in Fuzhou early season. The result indicated that ‘WX4’, ‘WX8’ and ‘WX9’ had better comprehensive performance on agronomic traits,grain quality, resistance and restoring force, and they could be used as restorer lines. By studying on key character of hybrids which obtained by waxy rice strains crossed with three waxy rice CMS-Lines, the combinations of waxy lines with ‘JianongWXA1’had better yield performance.Among these combinations, JianongWXA1/WX3 and JianongWXA1/WX4 accord with the standard of rice breeding in fujian early season on duration from seeding to heading and waxy endosperm quality, although their yield has lower than CK,but not significant. By combine the comprehensive characters of restorer lines and their hybrids,it was considered that restorer line ‘WX4’ has better performance.It has good value in conventional and hybrid rice breeding after being evaluated. ‘WX4’ was named ‘Fu Nuo Hui 1 Hao’.
