Allogamous reproductive behavior and the demonstrated existence of ample genetic variation for a number of agronomic traits in Andropogon gayanus suggest a substantial potential for genetic manipulation of the species. Possible breeding objectives are considered and appropriate breeding methods d...

Striga hermonthica is a parasitic weed that poses a serious threat to the production of economically important cereals in sub-Saharan Africa. The existence of genetic diversity within and between S. hermonthica populations presents a challenge to the successful development and deployment of effec...

The evidence for both between-and within-breed genetic variation for resistance to gastrointestinal (GI) nematode parasites is reviewed. It is concluded that much of the published research on breed characterisation for resistance suffers from poor experimental design. Prior to the initiation of a...

Genetic diversity of sub-Saharan African goats was assessed using 19 microsatellite markers. Breeds were sampled from eastern Africa (Maasai, Kigezi, Mubende, North West Highland, Arsi Bale), southern Africa (Ndebele, Pafuri) and West Africa (West African Dwarf, Maure, Djallonke). European breeds...

There are widely varying perceptions of the acceptability of Gliricidia sepium (Jacq.) Steud. to ruminants in different parts of the tropics. The possibility that there is a genetic basis for this apparent variation was investigated in a series of feeding experiments with small ruminants. The sam...
