- Atlantic (Solanum tuberosum)
ORIGIN: Selected from the progeny of a cross between Wauseon and USDA B5141-6
(Lenape) and was tested as B6987-56. Released by USDA breeding
program at Beltsville in 1978.
CHARACTERISTICS: A mid season cultivar widely grown for chipping.
Marketable yields are moderately high.
Plants are moderately large, with thick, upright
stems, and slightly swollen, sparsely pubescent nodes. Leaves are
bright, medium green, smooth, and moderately pubescent with prominent
wings, large asymmetrical primary leaflets and numerous secondary
and tertiary leaflets. Flowers are profuse with green, awl-shaped,
pubescent calyx lobes, pale lavender corolla, orange anthers and
abundant pollen. Tubers are oval to round with light to-heavy scaly
netted skin, moderately shallow eyes, and white flesh. Tuber dormancy
STRENGTHS & WEAKNESSES: With
high yield potential, high specific gravity and uniform tuber size
and shape, Atlantic is the standard variety for chipping from the
field or from very short-term storage. The cultivar is tolerant
to scab and Verticillium wilt; resistant to pinkeye; and highly
resistant to Race A of golden nematode, virus X and tuber net necrosis.
Tubers are susceptible to internal heat necrosis, particularly
in sandy soils in warm, dry seasons. Hollow heart in the larger
diameter tubers (>.83mm) can be serious in some growing areas.
