| 摘 要： | 通过利用4个常用两用核不育系与10个恢复系杂交．对F1代产量性状进行差异性分析、一般配合力比较、相关性分析和通径系数比较．结果表明．不同类型不育系配组后代性状中．均有不同的优势表现．对产量的主导影响因子不同．一般配合力表现差异较大．且对产量的相对影响重要性不同．在配制组合中，要综合兼顾各性状间的关系．不同不育系不同对待。

| Abstract: | Using 4 TGMS lines and 10 restorer lines to cross, their F_1 hybrids yield characters were compared by the analysis of variance, GCA, correlation and path. The results show that the characters of different type TGMS lines in their F_1 hybrids have different superior characters, different main effect to yield, different variance in GCA and different relative importance to yield. When taking TGMS to develop new hybrid rice combination,the relation of different characters should be considered according to the different TGMS lines. |
