University of Florida Potato Variety Trials Spotlight: 'Atlantic'1

Rodrick Z. Mwatuwa, Christian T. Christensen, and Lincoln Zotarelli 2

General Comments

‘Atlantic’ is a white-skinned, chipping potato commonly cultivated in Florida (Figure 1). The cultivar was released as a white mutant of the USDA breeding program. It was selected from a cross of Wauseon and Lenape (UDSA seedling B5141-6). 'Atlantic' was released in July 1976 by the Agricultural Research Service of the USDA, the Florida Agricultural Experiment Station, the Virginia Truck and Ornamentals Research Station, the New Jersey Agricultural Experiment Station, and the Maine Agricultural Experiment Station (Webb et al. 1976). Production and quality results provided in this spotlight are summarized from various trials conducted by the University of Florida over the past 18 years.

General Characteristics

'Atlantic' tubers are smooth with an oval to round shape. Its white skin has light to heavy scaly net touch. In heavy soils or areas with high organic matter the skin may be dark. The variety has white eye and internal flesh color. It is a high yielding variety with relatively low specific gravity adapted for Florida growing conditions (Tables 1, 2, and 3).

Season Length and Growth

The length of time from planting to harvesting is approximately 85 to 110 days depending on growing conditions during the season. Late in the season, tuber size should be checked regularly. 'Atlantic' typically shows rapid vegetative growth between 40 and 75 days after planting (Rens et al. 2015). It matures during the middle to late portions of the season.

Fertilization

University of Florida trial plots were fertilized with 200 to 230 lb/acre N. The first application of 100 lb/acre of N (granular) was incorporated in the bed prior to planting, followed by one or two side-dress fertilizer applications at emergence and/or at tuber initiation.

Planting

A seed piece of 21/2 to 3 oz is recommended for planting. The crop should be planted with 36 to 42 inches between rows, 7 to 10 inches between plants, and 3 to 4 inches deep. A seed rate of 2,000 to 3,000 lb/acre seed is expected.

Diseases

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 and during warm, dry seasons. In some areas, hollow heart can be serious in large tubers (diameter > 3 in), especially when growing conditions fluctuate during the season.

Seed Source

Seed for the trial was provided from many sources including Maine Farmer’s Exchange (MFX), University of Maine, USDA-ARS Presque Isle, and Maine growers.
