Potato (Solanum tuberosum L.; Solanaceae) is an important commodity in Indonesia as one of the main crop after rice. Recently some new varieties have been released, but their relationship have not been studied yet. The purpose of this research was to determine the relationship among nine varieties of potatoes. Phenetic analysis was conducted using 27 morphological character states, which was derived from stems, leaves, and tubers. The character states observed were scored, and further analyzed based on Unweighted Pair Group Method with Arithmetic Mean (UPGMA) method. The results showed a high diversity of morphological character states, of which 20 states were significantly different across the varieties. Phenogram indicated that the nine varieties of potato were classified into three main groups. While the first group was consisted of varieties of Cipanas, Granola, Atlantic, and Repita, the second group was housed of Manohara and GM 05. The third group was composed of Margahayu, Mb 17, and Maglia. This pattern of relationships can be used as one of the basis in the process of crossbreeding to assemble the new varieties. The crossbreeding will be better if it is made between distantly related varieties. © 2017 Author(s).
