粳稻6个亲本以完全双列杂交配成15个F_1组合。方差分析结果表明,8种性状的一般配合力方差和特殊配合力方差,差异都达到极显著水准。各亲本一般配合力因性状不同而有明显差别。各性状特殊配合力高的组合中,一般都有1个在该性状上一般配合力高的品种为亲本。粒重、株高、每穗实粒数、穗期的广义遗传力和狭义遗传力较高,这些性状可在早期世代选择。
The six parents of Japonica rice were crossed with 15 F_1 combinations by complete diallel cross. Analysis of variance showed that the variance of variance of general combining ability and the variance of combining ability of special characters of eight traits reached the extremely significant level. The general combining ability of each parent is obviously different due to different traits. In the combinations with high combining ability of each trait, there are generally one variety with high combining ability in this trait as the parent. Grain weight, plant height, grain number per panicle, broad heritability and narrow heritability at heading stage were all selected in the early generations.
