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.
The NCⅡ design method was used to analyze the general combining ability and the special combining ability of 7 parents (3 quality parents and 4 agronomic parents) of Flue - cured tobacco. The results showed that except for the special plant height and single leaf weight The general combining ability and the special combining ability of the rest of the traits reached significant or extremely significant level.According to the general combining ability effect, the special combining ability effect and the special combining ability variance, the genetic characteristics of the related traits And its application in breeding.
