This invention relates to ‘CX-1’, a new and distinct cultivar of sweetpotato, Ipomoea batatas, (L.) Lam. It is a distinct mutant from the sweetpotato variety, ‘Xushu 18’ from China, where other superior mutant cultivars of ‘Xushu 18’ have been registered. ‘CX-1’ is a distinct cultivar with high yield and higher dry matter than ‘Xushu 18’. By combining high levels of carbohydrate (mostly starch and some sugars) with high tonnage of roots per acre, ‘CX-1’ will produce very high levels of ethanol per acre compared to other temperate crops. This type of sweetpotato with its uniquely high dry matter, high starch content, and mealy texture can also be used to produce sweetpotato chips and fries that have significantly less oil than commercially available low dry matter sweetpotato varieties like ‘Beauregard’.
