Ranger Russet


Characteristics | Performance | Management Profile | Seed Spacing/Nitrogen Trials


The release of Ranger Russet was announced in 1991 by the USDA-ARS and Agricultural Experiment Station of Colorado, Idaho, Oregon, and Washington. Ranger Russet is grown for both the French fry, as an earlier frier than Russet Burbank, and the fresh markets.

Ranger Russet (A7411-2) was selected in 1977. It is an indeterminate variety whose vine is a medium-late maturation and is a medium-large plant. Frying quality of Ranger Russet is the same as for Russet Burbank at harvest and after 3-month storage. Sugar content is medium after storage at 45 F. Ranger Russet develops solids more rapidly than Russet Burbank and, therefore, are ready earlier for processing, about two weeks. Taste panel trials indicated similar baking quality between these two cultivars. Ranger Russet has been tested in the Western Regional Potato Variety Trials, and in various state and industry trials.
