A field trial was conducted in Florida with disease pressure from Xanthomonas perforans. Disease severity presented as percent infected tissue, converted from field ratings that were scored using the Horsfall–Barratt scale. Harvested tomatoes were graded and sized by USDA specifications to calculate the total marketable yield. The values shown are means ± standard deviation from at least four replicate plots of 10 plants each. Tomato plants expressing the Bs2 immune receptor gene were included as a resistant control.
