Abstract

The genetic diversity among 53 eggplant germplasms was analyzed by RAPD(Random Amplified Polymorphic DNA).9 polymorphic primers,screened out of 80 random primers,were used and produced 81 bands.Of them,46 bands(56.79%) were polymorphic.The genetic similarity indexes of all the germplasms varied from 0.72 to 0.99,suggesting that the genetic diversity among germplasms is narrow.The dendrogram constructed using the UPGMA analysis suggested that 53 germplasms could be divided into five groups.The results showed that the classification was not fully corresponded to the morphologic characters,and not associated with geological distribution too.
