Varieties Available
Currently, we deal only with four white varieties of processing potatoes. This includes Russet Burbank, Ranger Russet, Umatilla Russet and Shepody.
We have available this year:
- E3 Russet Burbank
- E3 and E4 Ranger Russet
- E1, E2 and E3 Umatilla Russet
- E1, E2 and E3 Shepody
Disease results are available upon request. All lots have been tested for nematodes on top of the Federal lab tests.
Russet Burbank
Medium to high yielding variety, attractive appearance, washes well at maturity. Long dormancy period, stores well. Requires a uniform moisture supply and long growing season to produce maximum quality tubers and to prevent knobbiness and second growth. To produce large tubers, plants must be spaced 30 to 45 cm apart. High total solids.
Umatilla Russet
Medium to high yielding variety, good tuber uniformity. Tuber specific gravity higher and more uniform than Russet Burbank; lighter fry color that holds up well throughout the storage season. Less susceptible than Russet Burbank to tuber shape and physiological problems induced by moisture stress. Relatively resistant to hollow heart, brown centre and internal brown spot. Medium long dormancy period.
Ranger Russet
Medium to high yielding variety; very resistant to heat necrosis and hollow heart; very susceptible to blackspot bruises; moderately susceptible to growth cracks. Good storability; short dormancy period; high specific gravity.
Resistant to metribuzin herbicide. Requires a long period after wine dessication to achieve good skin set. When intended for french fries, store at 7 to 8 °C and maintain high humidity; should not be stored beyond late February for processing as french fries. Seed potatoes should be stored at 2 to 3 °C to prevent excessive aging and sprouting.
Shepody
High yielding variety; uniform tuber size, high percentage of large tubers. Good resistance to second growth. Grades well with few culls. Good storage quality, needs through-the-pile ventilation. High specific gravity. For seed production, plants should be 15 to 20 cm apart and for processing, 30 to 40 cm apart. Reduced fertilization decreases the difficulty in top-killing.
NOTE: foliage is very sensitive to applications of the herbicide metribuzin (Lexone®, Sencor®) so this herbicide must be applied well before emergence.
