A high-yielding russet potato that was bred locally and should be officially released soon has shown promise as a short-season variety for processing thatâ€™s suited for storing at cold temperatures.
Rich Novy, a potato breeder with USDAâ€™s Agricultural Research Service in Aberdeen, made the initial cross for the russet line, A03141-6, in 2003.
Novy said the spud will be called Galena Russet, named after Idahoâ€™s scenic natural landmark Galena Peak. Located in the Ketchum area, Galena Peak, at 11,153 feet, is the stateâ€™s 94th tallest summit.Ã—
Novy said he made the initial cross for Galena from Premier Russet and an unreleased numbered line while seeking to breed a spud with cold-sweetening resistance. Cold sweetening occurs when the enzyme invertase changes sugars in potatoes stored in cold conditions, causing them to be dark when fried.
â€œThe big thing for it is its cold-sweetening resistance. You can store at colder temperatures than say Burbank or Ranger,â€ Novy said, explaining tuber quality can be maintained better when spuds are stored at a colder temperature.
Galena has already been approved for release by the Tri-State Potato Breeding Program: Potato breeders from USDA, University of Idaho, Oregon State University and Washington State University collaborate on their breeding efforts. An entity known as the Potato Variety Management Institute, based in Bend, Oregon, manages the royalties.
He said USDA must still approve the variety, which could happen by April or May. Commercial seed is available for industry trials.
â€œWeâ€™ve gotten good feedback from the processing industry,â€ Novy said.
â€œYou could use it both early and full season and it gives you some flexibility with your operation,â€ Novy said. Novy said Galena also has a fairly long tuber dormancy.
