| 摘 要： | 用郑三3号的3个亲本自交系,组配成6个正反单交组合和6个以单交为母本的三交组合,进行产量比较和性状调查。结果表明,6个单交组合之间的产量差异不显著,6个三交组合之间的产量差异亦不显著,说明这3个自交系相互间的配合力都很高,这是郑三3号的产量达到了优良单交种产量水平的内在因素。

| Abstract: | 6 single and three-way crosses produced by 3 inbred lines, which formed a three-way cross Zhengsan No. 3, were evaluated for grain yield and plant traits. The results showed that the differences of the grain yield were not significant neither among the single crosses nor among the three-way crosses. This indicated that all the 3 inbred lines possessed high combining ability, which ditermined the appraising grain yield of Zhengsan No. 3 . |
