利用多元分析法测定亲本间数量性状的遗传距离,进行了聚类分析。根据亲本间遗传距离大于类群间平均遗传距离结合选配杂交亲本的常规原则,选择亲本配制杂交组合,所得结果与夏谷育种的实践基本相符合。故从亲本分类入手,研究亲本选配方法,可增强对杂种后代的预见性。 Multivariate analysis was used to determine the genetic distance of quantitative traits among parents and the cluster analysis was conducted. According to the conventional principle that the genetic distance between parents was greater than the average genetic distance between the parents and the optional hybrid parents, the parents were selected to prepare the hybrid combinations. The results were in good agreement with the practice of summer wheat breeding. Therefore, starting from the parental classification, the study of the parental matching method can enhance the predictability of the hybrid offspring.
