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...

Manihot esculenta Cyanogenesis, the ability to produce hydrogen cyanide (HCN), is common to over 2000 plant species. In cassava, two cyanogenic glucosides, linamarin and lotaustralin, are produced in the leaves and stored inside vacuoles. Linamarase, an enzyme capable of hydrolyzing the glucoside...

Manihot esculenta.This paper which is based on information collected as part of Collaborative Study of Cassava in Africa (COSCA) provides information on cassava genotypes cultivated in sub-Saharan Africa. It shows that there is a high degree of turnover in the cassava genotypes cultivated. Farmer...

Cassava (Manihot esculenta Crantz) contains cyanogenic glucosides which lead to the release of hydrogen cyanide (HCN) after hydrolysis. A study carried out using six cassava populations revealed that the broad-sense heritability for HCN was relatively low at 34.58 and 32.18 percent in roots and l...

Stable as well as adaptable genotypes of high-yielding cassava cultivars, should be developed and made available to farmers, to ensure increases in cassava production in a target region or country in sub-Saharan Africa. As farmer-to-farmer contact is the primary means of diffusion of new crop var...
