Abstract: A variety type of sweetpotato, Ipomoea batatas, that was grown in such a manner to maximize the tonnage of storage roots produced. These types of sweetpotato can accumulate from 28% to 40% dry matter in the root which is mostly carbohydrate. By combining high levels of carbohydrate (mostly starch and some sugars) with high tonnage of roots per acre, this type of sweetpotato produces some of the highest levels of ethanol per acre found in any temperate crop. 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 and have an excellent, distinctive, texture and flavor.

Abstract: This disclosure relates to CX-1, a new and distinct variety of sweetpotato, Ipomoea batatas, (L.) Lam. It is a distinct mutant from the sweetpotato variety, Xushu 18 from China, where other superior mutant varietys of Xushu 18 have been registered. CX-1 is a distinct variety that has superior 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 some of the highest levels of ethanol per acre found in any temperate crop. 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 and have an excellent, distinctive, texture and flavor.

Abstract: 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’.
