Research on morphological variability and intra-specific classification of Indonesian water yam (Dioscorea alata L.) was conducted based on morphological characters (traits). Sample collection of Dioscorea spp. was done in some provinces in Indonesia including tubers, bulbils, stems, leafs, flowers, and fruits. Furthermore, tubers or bulbils were planted as live collections. Morphological characterization was conducted based on field and live collection data. Cluster analysis was carried out to identify key of intra-specific groups. The results showed that Indonesian water yam germplasm is classified into green and reddish-purple groups. Based on tuber shape and flesh color the green group was classified into 6 sub-groups: (1) white rounded to oblong, (2) white sweetish ob-ovate, (3) white ob-ovate to oblong, (4) yellow ob-ovate to oblong, (5) white to yellow long cylindrical, and (6) white oblong Papua water yam. Based on tuber shape, tuber skin, and color distribution in tuber flesh, the reddish-purple group is classified into 5 sub-groups: (1) purple long cylindrical, (2) purple ring white flash ob-ovate, (3) purple to red ob-ovate to oblong, (4) purple rounded to short cylindrical, and (5) yellow flesh purple skin water yam. The similarity of height within germplasm was due to vegetative propagation (clone) from tubers and bulbils.
