Strains of Pseudomonas solanacearum indigenous to the French West Indies were divided into four profiles of aggressiveness on tomato cultivars Floradel, Capitan, and Caraìbo, which are susceptible, moderately resistant, and resistant, respectively. Depending on the strain used, the resistance expressed in Capitan was dependent on temperature, whereas that in Caraìbo and Floradel was not. A link appears to exist between aggressiveness in Capitan and biovar type.
