Genetic incompatibilities in sweetpotato and implications for breeding end-user preferred traits

The objective of this study was to assess compatibilities among sweetpotato genotypes to select good parents for breeding end-user preferred traits in varieties for increased utilization in Ghana and beyond.   Sweetpotatoes utilization is low in Ghana due to lack of farmer and consumer preferred cultivars. Poor flowering and incompatibilities among …
