Abstract: Thirty-two jujube（Ziziphus jujuba Mill.）accessions from Anhui Province and fourty-two jujube cultivars from provinces around Anhui were analyzed by ISSR markers. A total of 241 markers were amplified from the 26 primers，of which 214 bands were polymorphic bands（the percentage of polymorphic band，PPB = 88.8%）. Revealed by NTSYS software，the DICE coefficient of 74 accessions ranged from 0.5936–0.9353. Thirty-two jujube accessions from Anhui Province amplified 219 loci，of which 186 loci were polymorphic（PPB = 84.93%）. Analyzed by NTSYS，the DICE coefficient among 32 accessions from Anhui Province ranged from 0.6267–0.9353，reflecting the high genetic diversity of jujube germplasms in Anhui Province. The UPGMA dendrogram demonstrated that the 74 accessions were clustered into 8 groups which were basically consistent with geographical origin. Most accessions from Anhui Province were clustered into independent groups which were far from other accessions and indicated that mutation promoted the evolution of jujube germplasm in Anhui Province.
