Genetic Diversity Analysis of Seedling Resources of Mango (Mangifera indica L.) by SSR Markers
Eightteen pairs of SSR primers were used to amplified SSR-PCR of the 116 mango germplasm resources,193 bands of 202 bands had polymorphism fragments,and the overall polymorphic loci percentage was 95.54 %,average of PIC was 0.57.UPGMA phenogram showed 109 seedling had abundant genetic diversity and the genetic similarity coefficients ranged from 0.6 to 1.0,which were clustered into four geographical regions groups,they are demark Guangdong and Hainan of local mango,Baise of Guangxi local mango,Nanlin of Guangxi local mango and the Yunnan Xiaoji mango.
