The 'Atlantic' is a midseason chipping potato variety. It was developed and released by USDA Agricultural Research Service scientists at Beltsville, MD in 1978. The variety is not under plant variety protection. It is a progeny of a cross between 'Wauseon' and 'Lanape'. It is widely grown for chipping right off the field or with short-term storage. Marketable yields are fairly high.
- Plants are moderately large and have thick, upright stems with slightly swollen nodes.
- Leaves are bright medium green and have prominent wings. The primary leaflets are large and asymmetrical with numerous secondary and tertiary leaflets.
- Flowers are abundant and are white with a light violet corolla. Pollen is also abundant and is produced on orange anthers.
- Tubers (potatoes) are oval to round with moderate to shallow eyes.
- Tuber skin is brown and light to heavily netted.
- Flesh is white and has a high specific gravity.
- It has moderate to high yields and is widely adapted, and used for potato chips.
- It is highly resistant to race A of golden nematodes, potato virus X, and tuber net necrosis, which is caused by potato leafroll virus.
- It is resistant to pinkeye and tolerant to common scab and Verticillium wilt.
- It is susceptible to potato virus Y. Hollow heart and heat necrosis can also be a serious problem potatoes.
