Identification of the Morphophysiological Characteristics of Cassava (Manihot esculenta Crantz) Based on Altitude

The study of the morph physiological characteristics of cassava is considered important for understanding the actual condition of local food resources. This research was conducted at Serdang Bedagai Regency from April - May 2018. Area of sampling decided was for each district was chose 1 Sub district, each Sub district was taken 3 villages and 3 farmers for each village. The objective of this study was to determine the type, kinship and physiological relationship of the distribution of cassava plasma (Manihot esculenta Crantz) based on altitude. The genotype types of cassava that have been found include White Klanting (S1), Red Klanting (S2), Jakarta (S3), Malaysia (S4), Gundoruwo (S5), Gundoruwo Hitam (S6), Thailand (S7), Yellow Potatoes (S8), and Adira (S9). The lowest euclidean values was showed on S1 and S6 with 10.084. In the dendogram there was two main parts, namely part 1 and 2 kinship with 25% dissimilarity scale. The highest water content was showed on Jakarta genotype with 66.22%, the highest glucose level was showed on Red Klanting genotype with 24.43%, the highest starch content was showed on Red Klanting genotype with 21.99% and the highest total chlorophyll was showed on Yellow Potatoes genotype with 88.25940 mg/g.
