摘　　要：为了解自主选育的水稻糯性品系的特性及在杂交稻育种中的作用,在福州早季对水稻早熟糯性品系的农艺性状、米质、抗性及恢复力进行了鉴定。结果显示:WX4、WX8和WX9 3个品系的农艺性状、米质、抗性和恢复力方面综合表现较好,是可以加以应用的恢复系。通过考察各品系与3个糯性不育系配组的杂交种关键性状,糯性品系与‘嘉农WXA1’配组产量优势比较明显。在与‘嘉农WXA1’的配组中,嘉农WXA1/WX3、嘉农WXA1/WX4组合生育期符合福建早季选育标准、糯性得以保持,产量虽然比对照低,但差异不显著。结合恢复系和杂交稻的综合性状考量认为:恢复系WX4综合性状好,在常规稻和杂交稻选育方面有较好的利用价值,WX4命名为‘福糯恢1号’。In order to learn the characteristics of rice waxy strains by self-selection and the role of rice waxy lines in hybrid rice breeding, agronomic traits, grain quality, resistance and restoring force were 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 the key characteristics of hybrids which were obtained by waxy rice strains crossed with three waxy rice CMS-Lines, the combinations of waxy lines with ‘JianongWXAl＇ had better yield performance. Among the combinations, JianongWXA1/WX3 and JianongWXA1/WX4 accorded with the standard of rice breeding in Fujian early season, and the waxy was maintained. Although the yield of the combinations was lower than that of CK, the difference was not significant. By combining the comprehensive characteristics of restorer lines and their hybrids, the restorer line WX4 had better performance and good value in conventional and hybrid rice breeding. WX4 was named ‘Fu Nuo Hui 1 Hao＇.
