Aggressiveness of Strains of Pseudomonas solanacearum from the French West Indies (Martinique and Guadeloupe) on Tomato

Abstract

Strains of Pseudomonas solanacearum indigenous to the French West Indies were divided into four prolifes of aggressiveness on tomato cultivars Floradel, Capitan, and Caraibo, 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 Caraibo and Floradel was not. A link appears to exist between aggressiveness in Capitan and biovar type.
