Abstract: In this study, nine species Polyscias leaves as experimental material, we analyzed the genetic diversity and relationship by ISSR markers, 9 stable and high polymorphism ISSR primers screened from 100 ISSR primers by optimized the system of PCR for Polyscias, a total of 70 bands were obtained by the polymorphic primers of 9 test specimens, including 61 polymorphic bands, the polymorphic percentage was 87.14%. The genetic similarity coefficients ranged from 0.346 9 to 0.816 3, suggesting that the substantial genetic divergence between some varieties. The clustering scheme showed that Polyscias had small differences of genetypes their genetic basis was comparatively narrow.

Key words: ISSR, Polyscias, foliage plants, genetic similarity coefficient, cluster analysis
