Superior is a white-skinned, white-fleshed, mid-season potato variety. It was released by the University of Wisconsin potato breeding program in 1962,[1] and is not under plant variety protection.[2] 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.
It is generally free from defects such as growth cracks, greening, secondary growth, heat necrosis, hollow heart, and vascular discoloration in tubers, but is susceptible to potato virus Y, potato virus X, and late blight.[1]
