Morphological Characteristics Variability of Arrowroot (Marantha arundinaceae L.). The arrowroot has been recognized by most society member of Indonesia as a source of potential foodstuf. The arrowroot has low glicemic index, and high carbohydrate content, high quality of flour and can replace position of wheat flour as food material and industry. Evaluation and characterization are needed to get informations of superior characteristic of arrowroot as source of genetic variability to develop promising new arrowroot varieties. The result showed that the morphological characteristic of 20 arrowroot accecions were not different on the qualitative characteristics. The characteristics of leaf colour, stem and stalk leaf colour, and white colour of tuber were not different among arrowroot accecions. The quantitative characteristics of tuber or rhizomes type (tuber length and tuber circle), plant height, number of tiller/hill, total leaf/main stem, leaf length and leaf width among accecions had low variability. The tuber weight per hill had positive correlation with plant height, number of leaf, tuber length and tuber circle and negative correlation with leaf length, leaf width and stalk length leaf.
