选用 6个不同来源的籼型核不育系与 7个优良恢复系按 6× 7不完全双列杂交方式配制 4 2个组合 ,估算了单株产量等 1 2个性状的配合力。结果表明 :①籼型两系杂交稻组合的产量和其他性状 ,同时受恢复系、不育系一般配合力效应和组合特殊配合力效应的作用 ;②不育系和恢复系的一般配合力效应比组合特殊配合力效应起着更为重要的作用
A total of 42 combinations of indica type CMS lines and 7 elite restorer lines from 6 different sources were used to prepare 12 combinations of 6 × 7 incomplete diallels to estimate the combining ability of 12 traits per plant. The results showed that: ①The yield and other traits of two-line indica hybrid rice combinations were affected by both the three lines of restorer, the general combining ability and the combining ability of CMS. ② The general combining ability of CMS lines and restorer lines Than the combination of special effects with a special play a more important role
