The book provides a reader with relevant information on Cowpea research and in particular the genetics of grain and vegetative biomass yields under well-watered and drought stress conditions during the vegetative phase of cowpea, establishing the yield penalty associated with vegetative-stage drought in cowpea in the parental lines and their F1 hybrids, in relation to hybrid vigour for drought tolerance and to identify the cowpea genotype with the highest tolerance to vegetative-stage drought among a set of nine genotypes reputed for drought tolerance. The book is relevant for Lecturers,...
