Interpretive Summary:

Technical Abstract: Jay Garner, Univ. of Idaho Extension Potato Specialist, obtained a tuber of Ozette (April of 1987) from a rancher on the Olympic Peninsula of Washington, not far from the Makah Indian Reservation. The Makah elders told Jay that Spanish explorers brought the potatoes to Neah Bay. The Spanish left them there when they abandoned their fort in 1792. The Makahs grew the potatoes for hundreds of years in the Lake Ozette gardens, 20 miles south of Neah Bay. The ground there does not freeze in winter, so any Ozette tubers left in the soil in the fall were ready to grow in the spring. Jay grew the Ozette in his Blackfoot garden in 1987. In Sept., Jay gave Dennis Corsini 8 tubers to test for virus content and to use as seed in 1988. In March.1988, Dennis found Ozette positive for PVX and negative for PVY, PLRV, and PSTV. In the Aberdeen field, the plants were vigorous, large, spreading, late, indeterminate growth, and with few light-purple flowers that turned white in the summer sun; no pollen was found. The tubers were long, with deep eyes, buff-beige skin, and with slightly yellow flesh. Attempted crossing was unsuccessful. The few flowers, lack of pollen, and lack of success in crossing attempts in the field are as expected with Russet Burbank. At Prosser, the cytoplasm was determined to also be that of S. tuberosum.
