The potatoes behind America’s potato chips are getting an upgrade.
Researchers at Michigan State University have developed five new potato varieties designed to help strengthen the U.S. chip supply by improving disease resistance, long-term storage and processing reliability.
The varieties — Manistee, Mackinaw, Petoskey, Huron Chipper and Blackberry — are the result of more than two decades of breeding research led by MSU potato breeder David Douches. Together, they were created to help growers produce potatoes that can store for months, withstand disease pressure and consistently fry light and crisp — even late in the processing season.
“Potato chips are made year-round, but potatoes are harvested once a year,” said Douches, professor in MSU’s Department of Plant, Soil and Microbial Sciences. “If a variety can’t maintain quality in storage or handle disease pressure, that affects the entire supply chain.”
