| 摘 要： | 利用2003G59S等4个粳型两用不育系与盐粳48等4个常规优良品种(系)共配成16个两系杂交水稻组合,分析了各不育系杂种7个主要农艺性状的杂种优势。结果表明:4个两用不育系的杂种均具有明显的产量超亲优势和竞争优势。其中以2003G59S最高,其次依次为G72S、G89S和G82S;16个具有产量竞争优势的组合中,以G82S/C258组合为最高,其次依次为G59S/辽盐92、G72S/盐粳48、G82S/盐粳48。

| Abstract: | Four Japonica photo-and themo-sensitive genic male sterile(PTGMS) lines and four regular rice varieties e.g. Yanjing48 were used to make 16 F1 hybrids. The heterosis of 7 main agronomic traits were analyzed. The results showed that in all F1 hybrids of four Japonica PTGMS line, there existed significant heterobeltiosis and standard heterosis in term of grain yield. 2003G59s showed the highest average F1 grain yield per plant, followed by G72S, G89S and then G82S; In all of the 16 F1 hybrids, G82S/258 was highest standard heterosis in grain yield per plant, follwed by G59S/Liaoyan92, G72S/Yanjing48 and G82S/Yanjing48. |
