In Thailand cassava breeding is the responsibility of the Rayong Field Crops Research Center of the Department of Agriculture (DOA), and of Kasetsart University (KU). From 1975 to 1992, six cultivars have been released for industrial use, i.e. Rayong 1, Rayong 3, Rayong 60, Rayong 90, Sri Racha 1...
In recent years (1990-1995) the cassava area in Vietnam has remained stable, or has increased slightly in the south due to the new demand for cassava roots used for starch processing. Therefore, our cassava breeding program, in collaboration with CIAT, has put a high priority on developing new va...
In the tropics, cassava starch is produced at artisanal and industrial scales. This paper focuses on a new methodology enabling the technoeconomical comparison of small-scale cassava starch manufacturing process (1–5 t of starch/day) in two markedly different contexts (Colombia and Vietnam). Meas...

Impact of integrated cassava projects in the North Coast of Colombia
During the past three years (1993-1996), cassava agronomy research, conducted by national programs in collaboration with CIAT and with financial support from the Nippon Foundation in Japan, continued as before but at a slightly lower level of activity. Major emphasis remained on soil fertility ma...
Despite its relatively recent introduction to Africa, cassava (Manihot esculenta Crantz) has become a major food crop adapted to a wide range of agro-ecologies that is grown by millions of small-holding farmers of sub-Saharan Africa (SSA), owing to its remarkable tolerance to an array of biotic a...

Cassava Monitoring Survey: Nigerian farmers’ preferences for varieties by gender and region, with reference to seed dissemination.
Drought is responsible for large reductions in cassava root yields. On-farm root yields can be improved two- to three-fold and quality of fresh and processed products improved by the adoption of recently improved production technologies. The potential usefulness is high for genetic, morphological...

An effective control for bacterial blight of cassava (Manihot esculenta), caused by Xanthomonas campestris pv. manihotis, requires the use of non-contaminated cuttings and seeds. Using classical agar plating techniques for screening planting material for contamination has not been very successful...
