A field genebank of 254 Kenyan sweetpotato landrace varieties collected from western Kenya was evaluated at the KARI regional research centre Kakamega between 1995 and 1997. The objective of the study was to identify virus resistant varieties with good agronomic and culinary qualities. Significant variation in yield, dry matter content and culinary quality existed among varieties. Early maturing varieties performed better than the other varieties. The sweetpotato virus disease affected over 60% of the varieties, with a higher frequency of susceptible accessions originating from Western Province. Selected promising accessions are undergoing further assessment in the Kenyan variety selection programme.
