Conference Paper 2010

Autor: Sanni, L.O. Abass, A. Dixon, A. Tarawali, G. Westby, Andrew

Cassava plays important roles. It is a famine reserve crop, a staple food for the rural populace and a cash crop for urban consumption. It is a source of industrial raw materials and earns foreign exchange. Unfortunately, the past decades witnessed too much emphasis on the production components o...

Cassava is an important food crop in the East African coastal lowlands. However, yields are low due to various reasons amongst which are pests and diseases. Cassava brown streak virus disease (CBSD) is one of the major diseases of economic importance in Kenya, Tanzania, Mozambique and Malawi. Yie...

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...

Most cassava (Manihot esculenta Crantz) improvement programs depend on the range of variability available within the cultigen for breeding varieties adapted to target environments. Efforts by some programs to introduce additional variability from wild Manihot species into cassava have led to impr...

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...

Multilocational trials were conducted in several agroecological zones in West Africa to assess the magnitude of genotype x environment (G x E) interaction and to identify stable varieties which could be used in breeding programs in the region. The reaction of the varieties to major cassava diseas...

Major upland soils in the humid and sub humid zones of West Africa consist of low activity clays (LAC) Alfisols, Ultisols and Oxisols. Alfisols which are less leached and have a high base saturation are more dominant in the sub-humid zone. Chemically they are more fertile, but they have a low str...

An agroecologically-based germplasm enhancement strategy to further broaden the genetic base of cassava in selected ecologies of Africa was initiated by CIAT and IITA in 1990. Crosses are being made at CIAT, in Colombia, using parents adapted to four different agroecologies of South America with ...

The cassava mosaic disease (CMD) is an economically important disease of the food crop cassava (Manihot esculenta Crantz) in Africa. Quantitative trait loci (QTLs) associated with resistance to CMD were identified using 132 F1 progeny derived from a cross between the CMD resistant accession TMSI3...
