Frost-resistant potato bred by researchers in the U.S. and Peru

The U.S. Department of Agriculture’s Agriculture Research Service (ARS) partnered with researchers in Peru and at the University of Wisconsin-Madison to breed a frost-resistant potato variety. Dubbed Wiñay, the potato is a cross between two wild potatoes native to South America, which showed the greatest ability to tolerate frost of the available species at the U.S. Potato Genebank.
