Conference Paper 1994

Autor: Ekanayake, I.J. Dixon, A. Asiedu, Robert Izac, A.M.

A substantial impact on Africa agriculture can be made through research on crop improvement for the extensive inland valley agro-ecosystems (IVS) extending from the humid forest to the savanna zones in sub saharan Africa. Systematic surveys of farmers have shown that cassava is a favoured upland ...

Production of improved water yam (Dioscorea alata) genotypes that are suitable for the preparation of amala (a popular darkish Nigerian food) would likely enhance the economic importance of the crop in Nigeria. Fermented flour (oven dried and sun dried) made from tubers of eight new improved D.al...

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...

Autor: Dixon, A. Asiedu, Robert Hahn, S.K.

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...
