Ranger Russet

The Ranger Russet is a late-maturing potato that is used for baking and processing into fries.[1] It was originally bred by Joseph J. Pavek of the USDA in Aberdeen, Idaho and released jointly by the USDA and the agricultural stations of Idaho, Washington, Oregon and Colorado in 1991. Ranger Russet is not under plant variety protection. It yields medium to high numbers of tubers with a short dormancy period.

Botanical Features

Agricultural Features


Ranger Russet has a dormancy period of approximately 100 days when stored at 45 F. This means if the potatoes are being stored to be used as seed they must be kept about 7-9 degrees cooler in order to prevent excessive sprouting and aging. Potatoes that are in storage to be used for processing can be stored in the same type of conditions that Russet Burbank can be stored at. If the potatoes are in storage for more than three months a chemical sprout inhibitor should be applied before 90th day. If the potatoes are immature or damaged fusarium dry rot can become an issue. It is also important that the storage unit is at a high humidity level to reduce the risk of pressure bruise. [2]
