Abstract: In this study, fluorescence-labeled simple sequence repeat(SSR)markers were used to fingerprinting the 64 Osmanthus fragrans cultivars under cultivation in China. Eleven pairs of SSR primers screened amplified 143 alleles,with an average of 13 alleles per locus. The average of Ho, He, I, Na and Ne was0.619 7, 0.848 3, 2.323 7, 17.833 3 and 8.228 2, respectively. The Asiaticus Group had a distance relationship with the remaining groups. Two of OF002, OF019, OSM63 and OSM63 could distinguish all of the O. fragrans cultivars. Sixty-four O. fragrans cultivars with different SSR fingerprints of each other could serve as the cultivars-specific patterns and as an important basis for cultivars identification.
