摘要： 应用NCⅡ设计方法对烤烟7个亲本（3个品质亲本作母本，4个农艺亲本作父本）进行了一般配合力和特殊配合力的分析，结果表明，除株高和单叶重的特殊配合力外，其余性状的一般配合力和特殊配合力均达显著或极显著水平。根据一般配合力效应，特殊配合力效应和特殊配合力方差，讨论了亲本品种（系）有关性状的遗传特点及其在育种中的应用。

Abstract: The general and specific combining abilities of seven flue-cured tobacco cultivars were analysed on the basis of NC II design. Among them three cultivars with good, qualitative characters were taken as female parents, while four cultivars with good agronomic characters, as male parents. The analysis results showed that the general and specific combining abilities of all the characters were significant or very significant except the specific combining ability of plant height and single-leaf weight. According to the effect of the general combining ability and the effect and variance of the specific combining ability, the genetic properties of some related characters of parent cultivars and their usage in breeding were discussed in this paper.
