用SSR标记分析辣椒属种质资源的遗传多样性

Analysis of Genetic Diversity of Capsicum Germplasm Resources by Using SSR Markers

利用21对引物在33个辣椒材料中共检测到54个等位基因，每对SSR引物检测到2-4个等住基因变异，平均为2.6个，说明辣椒种质资源的遗传多样性相对较少。通过MVSP3、13f软件对SSR数据进行聚类分析，把33个辣椒材料分为五类，同个种的辣椒种质资源基本聚在一起，说明用SSR标记采区分辣椒种质是可行的，是研究辣椒种质资源遗传多样性的有效手段。

Twenty SSR primers were used to study genetic diversity among 33 Capsicum germplasm resources that detected 53alleles. The average number of alleles per locus was 2.7 with a rang from 2 to 4. Using MVSP 3.13f to cluster analysis showed that 33 Capsicum germplasm resources could be classified into 5 groups ,the same species clustered together, and this indicated that it is feasible to using SSR markers to distinguish Capsicum germplasm resources, SSR markers is an available methods to study the genetic diversity of Capsicum germplasm resources.
