Sixty-two persimmon selections, including 16 Italian, 9 Spanish, 16 Japanese, 6 Korean, and 5 Chinese cultivars, were evaluated for genetic differences by AFLP analysis. Four-hundred-seventy characters were scored. Similarities were calculated by the method of Nei and Li. Relationships among cultivars were evaluated by UPGMA clustering and neighbor joining. Most cultivars were quite diverse (0.60 to 0.80 similarity between cultivars), while similarities among groups were generally less than 0.60. Both UPGMA and neighbor joining produced clusters for the European and Asian cultivars. Spanish and Italian cultivars did not cluster, while Chinese and Korean cultivars formed distinct groups. The diversity within groups was greater than the diversity between groups. In addition, the presence of several Japanese cultivars in the European group and Spanish cultivars in the Asian group suggest that similar, but diverse progenitors were used in the development of the current cultivars. Duplicate accessions of `Kaki Tipo' from different sources were clearly different by AFLP pattern (similarity less than 0.85).
