Table 2. Planting information for potato.

The University of Florida Potato Variety Evaluation Program screens new germplasm from public and private breeding programs and identifies the most promising cultivars for commercial potential, considering broad adaptability to Florida climate and conditions and market purpose: processing, fresh-market, and specialty-type varieties. The Florida Potato Variety Trial Report is available at https://hos.ifas.ufl.edu/extension/variety-trials/. A summary of the most popular potato clones for Florida is presented below. Key reference: total yield: high >300 cwt/A, medium-high 250–299 cwt/A; medium 200–249 cwt/A; low-medium 150–199 cwt/A. Tuber specific gravity (SG): high >1.075, medium-high 1.070–1.074, medium 1.065–1.069, low <1.064.
