Conference Paper 1992

Autor: Dixon, Alfred G.O. Asiedu, Robert Hahn, S.K.

Cassava (Manihot spp.) improvement strategies at the International Institute of Tropical Agriculture (IITA) are discussed here in relation to the main constraints, target ecologies and utilization of exotic germplasm. Germplasm generated from IITA populations and from other African or non-African...

Autor: Allem, A.C. Hahn, S.K.

The types of germplasm needed for the different agroecological zones where cassava is grown are outlined briefly in terms of what the main supplier (South America) has to offer. Africa's Atlantic coastal belt, its tropical rain forests, its extensive savannas, and the arid zones are examined in r...

Autor: Porto, M.C. Asiedu, Robert Dixon, A. Hahn, S.K.

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 ...

Six hybrid cocoyam clones from a uniform yield trial and a Local White accession from the germplasm collection were crossed in a diallel excluding reciprocals, in order to determine the inheritance pattern of resistance to cocoyam root rot blight complex (CRRBC) disease. The 21 progenies from thi...

Cassava is well recognized for its capacity to address food needs of vulnerable communities in unstable environments in SSA. IITA and colleagues in African NARS, in collaboration with CIAT and ARIs have played leading roles in the development of improved cassava varieties which are disease and pe...
