根据98个春小麦(包括硬粒小麦、小黑麦)亲本材料在定西唐家堡试点川旱地主要性状表现,对其进行了聚类分析。分析表明,亲本材料可以依其性状表现聚为若干类群。类群间性状表现差异较大,说明用聚类方法分析亲本是科学的。用最短距离法聚类结果与经验判断比较吻合。各种聚类分析法所得结果差异较大,但是对亲本研究来说,采用多种方法是有益的。
Based on 98 spring wheat (including Durum wheat, Triticale) parent materials in the main traits of experimental dry farmland in Dingxi Tang Jiabao, the cluster analysis was conducted. Analysis shows that the parent material can be clustered into several groups according to their traits. The differences in the traits among the taxa are quite different, indicating that it is scientific to analyze the parents by the cluster method. Clustering results using the shortest distance method are in good agreement with the experience. The results obtained by the various cluster analysis methods are quite different, but for the parental research, it is beneficial to adopt a variety of methods.
