The genetic diversity and interspecific relationship of 96 germplasms of Zoysia Willd.belonging to 5 species and 1 mutation were analyzed using SSR(Simple Sequence Repeat) markers.The results showed that:(1)Total 282 bands were detected by 29 pairs of SSR primers,and 272 of 282 were polymorphic with PPB(Percentage of Polymorphic Bands) at 96.45%,the Nei's gene diversity index(H) was 0.2203,and the Shannon diversity index(I) was 0.3504,indicating a high level of genetic diversity in zoysiagrass.(2) The GS(ge...
