Data capture experiment on sweet potato varietal identification in southern Ethiopia. Three household-based methods of identifying varietal adoption are tested against the benchmark of DNA fingerprinting: A) Elicitation from farmers with basic questions for the most widely planted variety; B) Farmer elicitation on five sweet potato phenotypic attributes by showing a visual-aid protocol and C) Enumerator recording observations on five sweet potato phenotypic attributes using a visual-aid protocol and visiting the field.
