Abstract

Cassava is one of important sources of carbohydrate and potential to developed as an alternative food diversification. Morfological and nutritional value characterization of cassava’s tuber including β-caroten, protein, Fe and Zn, has been conducted on seven genotypes of cassava. The seven genotypes tested were Adira 1, Adira 4, FEC 25, Mentega 1, Mentega 2, Ubi Kuning and Roti. Tuber of characteristic of seven genotypes showed variation in term of colors of the outer skin, inner tuber’s skin and  flesh, root shapes, average tuber weight per plant, length and diameter of the tuber. There was a positive correlation between diamater and weight tuber per plant.  Nutritonal content  of seven cassava genotypes tested were varied  with  value ranges   0,011-0,026 ppm, 1,19-2,6%, 34,46-133,07 ppm and  6,63-18,95 ppm for β-caroten, protein, Fe and Zn respectively.  The tuber with higer β-caroten content  up to 0,011 ppm possessed yellow flesh color. Based on nutritional value  data it was found   that Mentega 2   containing highest β-caroten, protein, Fe, and Zn.than the others genotypes
