Vamas 1, a new early root bulking, high-yielding, high-starch content cassava variety

Abstract

A good variety of cassava is important factor in increasing the productivity. If the productivity of cassava is increase, the competitiveness of cassava will increase. Vamas 1 is new variety released 2020 by Indonesian Government. Based on multi-location trial during 2015-2018 in 8 location in Lampung, the fresh tuber yield in 7 months of Vamas 1 was 25% higher that UJ3, equal to IDR 64,600,00,-/ha if the price of cassava IDR 1000,-/kg and 15% higher than UJ5, equal to IDR 6,460,000,-/ha. Starch yield of Vamas 1 was 39% higher than UJ3, equal to IDR 16,056,000,-/ha and 23% higher than UJ5, equal to 10,736,000,-/ha. Plant height of Vamas 1 was lower than UJ5. Starch content of Vamas 1 was higher than UJ3 and UJ5. Vamas 1 was shown moderately resistant against mite insect under artificial screening which is similar to UJ3 and UJ5. Vamas 1 has shown moderately resistant to cassava root rot desease under artificial screening, while the checks showed the susceptible. HCN content of fresh tuber of Vamas 1 was 19.68 ppm less than UJ3 (48.9 ppm) and UJ5 (40.56 ppm) as checks.
