Abstract 25 SSR primers were used to study the genetic diversities among 20 accesions of tomato（Lycopersicon esculentum Mill.）germplasm resources detected from 66 bands．There were 52 bands which had polymorphism，and the polymorphism rate was 78.8%．The results of genetic distance analysis showed that the genetic distance of 20 tomato materials were 1.489 2-9.180 6．There were 18 tomato materials which the genetic distance was more than 7，No.1 and No.15 had the largest genetic distance．That was 9.180 6．The result of cluster analysis showed that 20 tomato germplasm resources could be classified into 4 groups.
