Abstract: Five special primer pairs of chloroplast genome were used to amplified chloroplast DNA (cpDNA)regions in 8 Diospyros species including 32 genotypes. The products were digested by seven restriction enzymes. The results showed high interspecific cpDNA variations within the genus Diospyros. Twenty-two D. kaki genotypes were detected no visually variation in this study. D. kaki had closely relationship with‘Jinzaoshi’,followed by D. oleifera,D. artrotricha,D. lotus and D. glaucifolia,but distant from D. virginiana and D. cathayensis in diagram based on the UPGMA cluster analysis by NTSYSpc 2.10e program. Wild persimmon(Zhejiang)is a variety varietas of persimmon. The result showed that wild persimmon(Zhejiang)is not closely similar to D. kaki.

Key words: Diospyros kaki, cpDNA, PCR-RFLP, genetic diversity, genetic relationship
