Abstract：Genetic diversity in salt tolerant eggplant（Solanum melongena L.）cultivars was analyzed with RAPD technology．The results showed that 10 primers were screened from 100 RAPD primers and 102 polymorphic bands were amplified，the polymorphic band percentage was 77.45%．Clustering analysis showed that the value of genetic variation indexes of 14 eggplant cultivars based on the RAPD data were varied from 0.316 to 0.975．They could be classified into 3 groups at coefficient of 0.47 with UPGMA method，and most of the samples（85.71%）were gathered in the 3rd group（cultivated cultivars），indicating the collected germplasm with closer blood relationship.
