Abstract 105 eggplant（Solanum melongena L.）SSR markers were used to analyze the genetic polymorphism of 34 eggplant high generation materials．The result indicates that there are 47 markers showing polymorphisms among the tested materials which have 148 polymorphism sits．The polymorphism information content（PIC）varies from 0.025 4-0.909 3，showing high genetic polymorphism. The similarities coefficient of the tested materials was between 0.63 to 0.93，implying little genetic differences and relatively narrow genetic base．By UPGMA cluster analysis，we classified the tested materials into 2 clusters and 4 sub-clusters．The result of SSR molecular marker is almost the same with that of fruit trait cluster analysis.
