The starchy staples of cassava (tuberous roots) provides more than half the calories consumed by more than 200 million people in sub-Saharan Africa, and the leaves are often used as a vegetable providing protein, vitamins and minerals. The cyanogenic potential of cassava has often been cited as a...

Breeding of cassava for low cyanogenic potential: problems, progress and prospects
The distribution of the cyanogenic potential in cassava germplasm has been found to be a continuum from very low values to high levels. Within the same genotype, the cyanogenic potential is affected by the planting season; it is low when planted at the beginning of the rainy season, and high when...

Genotype environment interactions for cyanogenic potential in cassava
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...
This paper is based on information collected from about 600 villages in the ten largest cassava-producing countries within the framework of the Collaborative Study of Cassava in Africa (COSCA). The objective of the paper is to show that growth in cassava production in the region will depend more ...

Importance of cassava processing for production in subSaharan Africa
Cassava roots, a major food in Africa, contain cyanogenic glucosides that may cause toxic effects. Malawian women farmers considered fields of seemingly similar cassava plants to be mixes of both ‘cool’ and ‘bitter’ cultivars. They regard roots from ‘cool’ cultivars as non-toxic. Roots of ‘bitter...
