Mosaic resistant cassava varieties with high starch content

The Hung Loc Agricultural Experimental Research Center is actively combating cassava mosaic disease by developing and distributing resistant cassava varieties such as HN1 and HN5 in Dong Nai province, which have demonstrated high yields and starch content. Despite the high demand, the low multiplication rate of these varieties has led the Center to adopt rapid multiplication techniques. In collaboration with the International Center for Tropical Agriculture (CIAT), the Center is crossbreeding local varieties with imported resistant ones, resulting in several successful varieties like HN3, HN5, HN1, HN36, HN80, and HN97, which show strong resistance to the disease. A hybrid garden in Don Duong district, Lam Dong province, supports this research. The Ministry of Agriculture and Rural Development is backing efforts to diversify and supply these resistant varieties to farmers, including testing the promising TMEB419 variety from Africa.

Replicating cassava varieties resistant to mosaic According to Hung Loc Agricultural Experimental Research Center, cassava mosaic is a dangerous and serious disease, greatly affecting the yield as well as the quality of tubers, increasing the cost of disease prevention and control, leading to a decrease in economic efficiency of cassava growers in many localities, including Dong Nai province. Faced with this situation, the Center has conducted research on rapidly replicating cassava varieties HN1 and HN5 and transferred them to farmers in Nhon Trach, Long Thanh and Xuan Loc districts. Through actual production, the HN1 cassava variety yields about 42.5 tons/ha and the HN5 variety yields from 38 - 43.7 tons/ha, both of which have high starch content, straight stems, and are stronger than traditional varieties; at the same time, they are considered suitable for ecological conditions, soil and climate in Dong Nai. After implementing highly effective models, Dong Nai province has ...
