ABSTRACT The study was carried out to understand the genetic basis for yield under drought environments, and to map quantitative trait loci associated with yield and yield related components under drought stress in sweetpotato. The sweetpotato BxT mapping population, generated from a cross between sweetpotato varieties Beauregard and Tanzania was used for this study. Genotypes were evaluated in irrigated and drought environments to evaluate the effect of drought on yield and yield related p...
ABSTRACT The number of people suffering from chronic undernourishment in sub-Saharan Africa has increased. The potential of the cowpea to be the crop of the future to address food and nutrition insecurity is evident in sub-Saharan Africa. This study was carried out to evaluate cowpea accessions for early maturity and drought tolerant genotypes with potential for higher yields for smallholder farmers in South Sudan. One hundred and six cowpea accessions were sourced from different backgrounds....
ABSTRACT Studies were undertaken to identify the constraints to increase sweetpotato utilization in Ghana and to develop end-user preferred varieties that would increase utilization in Ghana and beyond. A survey was conducted using Focus Group Discussion (FGD) followed by administration of Semi-Structured Questionnaire. This was done in some selected communities in Ghana where sweetpotato is popular in February 2012. Sweetpotato germplasm was also collected from farmers’ field in these area...
