Superior (potato)

'Superior' is a white-skinned and white-fleshed, midseason potato variety. It was released by the University of Wisconsin potato breeding program in 1962 and is not under plant variety protection.^[1] 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.

Botanical features

• Superior is self-fertile
• Tubers (potatoes) are oval to round with medium-depth eyes.
• Tuber skin is white and may become lightly russeted as it matures.
• Flesh is white and has a high specific gravity.

Agricultural features

• High yields, it is used for potato chips, but grows best in cool climates.
• It has moderate resistance to common scab and Verticillium wilt
• 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.
