Conference Paper 1977

Autor: Hahn, S.K. Howland, A.K. Wilson, J.E.

The constraint to the production of the root and tuber crops, cassava, yams and sweet potato in Nigeria and Africa were stated. Breeding methods most appropriate to these crops were discussed in terms of mating systems, creation of source populations, selection, and use of selections. Intervariet...

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...

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...
