Abstract: Phylogenesis of 56 cultivated radish germplasm from different countries or regions was analyzed with amplified fragment length polymorphism (AFLP). A total of 327 bands were detected with 8 pairs of informative AFLP primers among the accessions tested. Of them, 128 bands (39.1%) were polymorphic, indicating abundant genetic diversity existing among the cultivated radish. The 56 cultivars were clustered into 5 groups and 9 subgroups by cluster analysis, and 4 groups and 7 subgroups by principal coordinate analysis. The two methods above exhibited similar phylogenesis among the tested cultivars. The results from molecular classification were almost coincided with germplasm phenotypes.
