采用15个形态性状对43份山羊豆种质资源进行遗传多样性分析,结果表明,山羊豆种质资源遗传变异丰富,多样性指数为1.863,其中俄罗斯南部地区可能是山羊豆形态多样性的分布中心。基于形态性状的聚类分析把43份材料聚为5类,其中第1类15份资源的株高和主茎分枝数明显高于其他类,且叶量丰富,营养性状表现良好;结实性状中荚果长和百粒重较大,综合性状表现较好,可以从中筛选合适的材料作为引种驯化和育种的试验材料。
The genetic diversity of goat bean germplasm resources was analyzed by 15 morphological traits. The results showed that the genetic diversity of goat bean germplasm resources was rich, with a diversity index of 1.863. The distribution of morphological diversity of goat bean may be found in the southern part of Russia. center. Based on the morphological traits clustering analysis, 43 materials were grouped into 5 categories, of which 15 were the first category, and the branches and branches were significantly higher than those of the other categories, with abundant leaves and good nutritional traits; The pod length and the hundred kernel weight are bigger, and the comprehensive traits are better. The suitable material can be selected as the test material for introduction, domestication and breeding.
