Abstract: ISSR-PCR was used to detect the genetic diversity and relationship of 85 chrysanthemum cultivars. ISSR fingerprinting amplified by 22 ISSR primers revealed a total number of 160 unambiguous bands, of which 148 ones were polymorphic and the polymorphism frequency was 92.5%. As analyzed by POPGENE 1.31, the average value of effective number of alleles, Nei's gene diversity and Shannon's information index were 1.6013, 0.3485 and 0.5162, respectively. As analyzed by SPSS 11.0, the similarity coefficient between cultivars ranged from 0.294 to 0.802. These 85 chrysanthemum cultivars were divided into six groups by UPGMA (unweighted pair group method with arithmetic average) based on Jaccard coefficient. The genetic relationship of 85 cultivars was related to their petal types.
