Cassava (Manihot esculenta Crantz) is one of the most important food crops grown in the tropical regions of the world. Even though cassava is also cultivated and consumed in southern China, there is little knowledge of the composition of the cassava grown here. Therefore, 16 cassava germplasms collected from Hainan Province in China were used in the present work to determine the proximate composition, amino acid, mineral, and hydrogen cyanide contents of their roots. The results showed significant differences among the cassava germplasms. The cassava germplasms contained 85.56 - 90.50 g/100 g carbohydrate, 0.03 - 1.28 g/100 g crude lipid, 1.41 - 4.74 g/100 g crude protein, 2.90 - 8.60 g/100 g moisture, and 2.89 - 4.38 g/100 g ash. The mineral contents were 62.89 - 467.36, 425.01 - 1474.71, and 070 - 7.95 mg/kg for Ca, Mg, and Pb, respectively; and 1523.08 - 4749.46, 75.57 - 766.33, 9.57 - 282.83, 4.48 - 26.69, 0.75 - 373.60, and 10.43 - 29.04 mg/kg for K, Na, Zn, Mn, Cu, and Fe, respectively. The HCN content ranged from 0.32 - 1.53 mg/g. Among the 16 cassava germplasms, ZMH1071, ZMJ615, and SC12 yielded higher carbohydrate content and lower HCN content, making them suitable for direct consumption or processing; and germplasm M484 yielded high cyanide and carbohydrate content, making it more suitable for starch processing.
