SSR Analysis Of Genetic Diversity And Genetic Relationship Among Ecotypes Of Adzuki Beans (Vigna Angularis) Germplasm

Adzuki bean (Vigna angularis) originated from China, and had long cultivation history. It is very important to detect the genetic diversity of wild ,weedy and cultivated adzuki beans for further researching the process of diffusion, evolution and the origin of adzuki bean germplasm resources.560 accessions of adzuki bean from China, Japan, Korea, Bhutan, and Vietnam were analyzed using SSR markers. 86 polymorphic bands were detected by 11 SSR primers. There were species-specific bands in the three races ;The order of Genetic dispersion was: wild adzuki bean>weedy adzuki bean>cultivated adzuki bean, and the order of Gst was: wild adzuki bean
