Umatilla Russet is a cultivar of potato (Solanum tuberosum) developed in the United States. It is classified as a russet‑type potato, characterized by its brown, netted skin and elongated shape.
Development and Release
The cultivar was bred through a collaboration between the United States Department of Agriculture (USDA) Agricultural Research Service and Oregon State University. It was released for commercial production in the early 2000s, with the name reflecting its association with Umatilla County in Oregon, a region noted for potato breeding programs.
Agronomic Characteristics
- Growth habit: Medium‑tall plant with moderate to late maturity.
- Yield: Reported to produce high tuber yields under suitable agronomic practices.
- Disease resistance: Exhibits resistance to several common potato ailments, including Phytophthora infestans (late blight) and Verticillium wilt; moderate susceptibility to common scab.
- Tuber traits: Large, elongated tubers with a russeted skin; flesh is white, low in sugar, and retains shape after cooking.
Uses
The tuber’s texture and low reducing sugar content make it suitable for processing into french fries and chips. It is also used for fresh market sales where russet potatoes are preferred for baking and boiling.
Naming
The designation “Umatilla” references the cultivar’s development in the Umatilla region of Oregon, while “Russet” denotes its skin type, aligning with common naming conventions for russet‑type potatoes.
Current Status
Umatilla Russet remains a regionally cultivated variety, primarily grown in the Pacific Northwest of the United States. Information on its adoption outside this area is limited.
