Abstract

Abstract: 12 primers were selected from 100 ISSR primers. 116 DNA fragments were amplified from 57 samples and each primers resulted in 9.67 DNA fragments. 84 fragments were polymorphic ( percentage of polymorphic bands was 71% ). The value of Neips genetic similarity (GS) indexes of 57 cultivars based on the ISSR data varied from 0.51 to 0.98, with an average of 0.84, suggesting that the genetic diversity among cultivars of China Southern Region is short. Cluster analysis with UPGMA method showed that the cultivars tested in this study could be divided into six groups. The results according with the pedigree relations had no connection with regions of cultivars origin.

Key words: Eggplant, Genetic diversity, Genetic relation, ISSR
