Keep Your Eyes on the Fries

Next time you go to McDonald's, there's a good chance you'll be eating an ARS-developed French fry. ARS scientists released two varieties of potatoes—'Clearwater Russet' and 'Blazer Russet'—used by McDonald's for French fries. The company has a high bar for its potatoes, having accepted only seven varieties to use in its fries over the years.

Potatoes are highly perishable, and the crop must be consumed, processed, or stored cold immediately after harvest. However, ARS potato breeders were able to release new potato varieties resistant to problems that develop during storage and to internal heat necrosis.
