Combining ability and heterosis for yield and drought tolerance traits under managed drought stress in sweetpotato
Drought is among sweetpotato production constraints in sub-Saharan Africa. Two studies were conducted on 15 F1 sweetpotato families (G1-G15) generated using a half-diallel mating scheme of sixExpand

Combining ability and cultivar superiority of sorghum germplasm for grain yield across tropical low- and mid-altitude environments
Abstract Sorghum grain production in sub-Saharan Africa is constrained by the fact that farmers’ choice of improved varieties is limited. Hybrid cultivars have been shown to be more productive forExpand

Identification of new sources of resistance to Striga gesnerioides in cowpea germplasm
There have been reports of breakdown of striga resistance in previously resistant cowpea cultivars in Burkina Faso. This could be attributed to new striga races emerging or to an increase in theExpand
