Abstract

Cassava has a variety of uses, including food, animal feed, and as an industrial raw material for a variety of products. Cassava is more resistant to global climate change, so it will be the food source of the future. Land for cassava cultivation will shift to marginal land in the medium and highlands as a result of land conversion because it cannot compete with high-value food commodities. Based on this, cassava that is adapted to land at medium to high altitudes is required (at least 700 m asl). The results showed that of the 44 clones tested and two control varieties, clone 344 (55.07 t.ha-1) produced the highest tuber yield (2.11 times that of the control varieties). Clones 344 had the highest harvest index of 0.6, the highest dry matter content of 44.18%, the highest starch content of 22.08%, and the highest starch yield of 12.17 t.ha-1. Clones 368 (41.8 t.ha-1), 584 (47.09 t.ha-1), 222 (40.01 t.ha-1), 712 (42.46 t.ha-1), and 183 also had tuber yields greater than 40 t.ha-1 and relatively high branching (42.90 t.ha-1). Tuber yield averaged 17.76 t.ha.-1 for two control varieties.
