A neighbor-joining phylogenetic tree of 1,603 accessions, Japanese (n = 998) and exotic cultivated soybeans (n = 341), Japanese (n = 74) and exotic wild soybeans (n = 190), based on the allele sharing distance. The letters in square bracket for Japanese clusters are phenotype information such as the representative ecological types followed by DF, days to flowering, FH, period from first flowering to start harvest, PH, plant height, SW, 100 seed weight, and seed coat color. Numeric characters after DF, FH, PH and SW and in a round bracket indicate that average and standard deviation among accessions in the cluster, respectively.
