Superior is a white skin and white flesh 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 chipping right off the field. Marketable yields are fairly high.
