This study estimated the amount of loss in storage roots caused by various levels of damage caused by sweetpotato weevils (Cylas spp). Seven varieties of sweetpotato (Ipomoea batatas L. (Lam)) were evaluated in three production sites in northern Ghana for two years (2014 and 2015). Yield data for...

A major objective of breeding at the Sweetpotato Support Platform for West Africa in Ghana, is the development of non-sweet cultivars suitable for use as staple foods, or in fried and other processed products. This priority was set during stakeholder consultations when establishing the program, a...

Commercialization of sweetpotato vines is persistent if multipliers show evidence of superiority of their vines. This study aimed at evaluating the effects of net tunnel source and of pathogen tested planting material compared to “apparently” healthy vines on yield and health status at three defi...

The current study was aimed at identifying mega‐environments in Ghana and evaluating adaptability of superior sweetpotato [Ipomoea batatas (L.) Lam.] genotypes from a targeted breeding effort. Three sets of genotypes were evaluated in multi‐environment trials (MET). Twelve sweetpotato varieties w...
