紫云英品种综合性状聚类研究是品种资源研究的一个组成部分.过去紫云英品种一般按生育期长短分早熟、中熟和晚熟三种,这一分类法只是把生育期单一性状作为聚类依据. 综合数值分析法是运用数学方法将参与聚类品种主要经济性状信息总量的70%以上信息,组成品种性状的主成分方程,绘制具有类间界线的散点图,能标出品种 Astragalus varieties comprehensive trait clustering study is an integral part of the variety of resources.In the past, the average age of the species of Astragalus according to the length of the period of premature, medium and late maturity of three, this classification is only the single growth trait as poly Based on the comprehensive numerical analysis method is the use of mathematical methods will be involved in more than 70% of the total information of the main economic traits clustering varieties of information, the composition of the traits of the principal component equation, drawn with the class boundary line scatter plot, can mark the species
