Superior is a white-skinned, white-fleshed, mid-season potato variety. It was released by the University of Wisconsin potato breeding program in 1962, and is not under plant variety protection. It is a progeny of a cross between 'B96-56' and 'M59.44' and was first grown in 1951. 'B96-56' was also a parent of Kennebec. Like the potato variety Atlantic, Superior is widely grown for potato chip manufacturing right off the field and marketable yields are fairly high.
