摘要: 为了解自主选育的水稻糯性品系的特征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‘WX9’三个品系的农艺性状、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。通过考察各品系与三个糯性不育系配组的杂交种关键性状看,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,经评价鉴定后可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’。

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’.
