Antioxidants, such as polyphenols and carotenoids, are present in potato and reported to have positive effects on human health. For Ecuadorian landraces there is a lack of data on these compounds. The present study aims 1) to characterize potato landraces from three areas in Ecuador for dry matter, total polyphenol and total carotenoid contents and 2) to determine if farmer preferences for certain landraces are based on characteristics related to nutritional value. We evaluated 23 potato landraces collected from farmer’s fields and organized workshops in the areas to collect information on the preferences of local farmers. We found varying levels of dry matter, total polyphenol and total carotenoid contents among Ecuadorian potato landraces, some even comparable to improved varieties. The extent of the use of these potato landraces by farmers and breeders is discussed.
