| 摘 要： | 选择具有广泛代表性的6个不育系和9个恢复系，采用NC II交配设计分析12个农艺性状的配合力。结果表明：①除主茎剑叶长、结实率和千粒重三性状非加性效应不明显外，其他性状的加性效应和非加性效应均有显著作用，且均以加性变异为主，但单株产量、相对日产量及单株穗数三性状非加性变异较大。②主茎剑叶长、穗长和千粒重三性

| Abstract: | 15 widespread elite indica parents, including 6 CMS lines and 9 restorers, were chosen, and a 6 ×9 NC II mating design was completed. The combining ability of 12 agronomic characters was determined. The results showed that；① Both additive and nonadditive effects were significant in all 12 charact |
