SSR and SRAP Analysis of Genetic Diversity of Stylosanthes
SSR and SRAP molecular markers were used to study genetic diversity among 20 Stylosanthes cultivars.41 of 113 SSR and 25 of 224 SRAP pairs of primer were employed. 229 SSR and 359 SRAP markers were obtained respectively, with polymorphism 76.86% and 74.65%, respectively. The genetic similarity coefficients were0.65~0.90. It indicated that Stylosanthes had an abundant genetic polymorphism in different cultivars. In addition,using UPGMA-clustering analysis, the materials could be divided into three groups, and groups I could be further divided into four sub-groups.
