Origin and Breeding History

Even without an official release by the University of Wisconsin, Snowden has grown rapidly in its popularity in the 1990s. Its first published description was by Peloquin, SP, C Thill, and AD Pavlista in the newsletter Nebraska Potato Eyes volume 6 issue 1 in Spring, 1994.

This cultivar is designated for the potato chip market. Snowden (W 855) was selected in the late 1970s in Wisconsin from a cross between Wischip and B5141-6, and named in 1990.

Selection and early testing were done by Dr. Stan Peloquin and Mr. Donald Kichefski at the UW-Lelah Starks Potato Breeding Farm, Rhinelander, WI. In 1993, 7,230 acres of certified seed were grown nationwide ranking eighth in acreage; a fourth (1730) of this acreage was in Nebraska, second to Wisconsin.

It is now a standard in the North Central Regional Trials. It is very much like Atlantic except that it chips out of 45F storage without reconditioning.
