From Cultivariable. A Bolivian heirloom variety. The name translates more or less to “fine white.” It is a high dormancy (stenotomum type) diploid. Tubers are small, typically reaching two to three inches, with white skin and flesh. This variety was provided by the USDA Potato Introduction Station as PI 642442. While the tubers are not particularly exciting to look at, this variety carries a range of useful disease resistances, including both late blight and bacterial wilt, so it is potentially valuable for breeding with other diploid potatoes.
