Sweet potato is a source of carbohydrates, widely cultivated by the people of Papua. Sweet potato have a variety of different types and characters. This diversity has an important in the process of selecting and assembling new superior varieties. Identification based on morphological characters on leaves and tubers can be used to the similarities and differences in plants, both quantitatively and qualitatively. The sugar level in sweet potato tubers needs to be known, because it is related to use as food for patient with degenerative diseases. The aim of the study was to identify the morphological characters of leaves and tubers, as well as sugar level in three sweet potato accessions cultivated by the local community. Identification of morphological characters of leaves and tubers used descriptive methods, while identification of sugar level used experimental methods. The results showed that (1) the morphological characters of the leaves and tubers of the three types of sweet potato cultivated by the local community were different, both quantitatively and qualitatively. (2) The highest sugar level is found in boiled and baked light yellow sweet potatoes. The lowest sugar level was found in boiled white sweet potatoes (3.570brix) and creamy sweet potatoes that were baked (3.130brix). White and creamy sweet potatoes are more suitable for people with degenerative diseases.
