洋葱主要品质性状配合力分析

Analysis on Combining Ability for Main Onion Quality Characters

结果表明这 6个性状的一般配合力方差和特殊配合力方差在模型 和模型 下均达到显著水平 ,说明基因的加性效应和非加性效应对这 6个性状的遗传均有一定的作用 ;亲本 2和 6的 6个性状一般配合力均较高 ,是比较好的杂交育种材料 ;亲本的一般配合力和组合的特殊配合力表现既有相对一致之处 。

The results from the variance analysis of combining ability showed that general combining ability (GCA) and special combining ability (SCA) were very significantly for six characters in modelⅠand modelⅡ. Variety 2 and Variety 6 have better GCA in all characters, so they were very useful varieties for quality breeding. But it also showed SCA was not always accord with GCA.
