Bacterial wilt caused by R. solanacearum is a constraint that limits the production of solanaceous in Côte d'Ivoire. The genetic control, which is more widely used, comes up against the genetic and phenotypic variability of the strains. The objective of this study was to screen commercial and traditional varieties of Solanaceae against Ivorian strains of different phylotypes to assess their spectrum of resistance to the disease. The level of virulence of the five strains of R. solanacearum was evaluated in semi-controlled conditions against eight varieties of Solanaceae (pepper, eggplant and tomato). Four groups of strains were identified according to the level of virulence. Group 4, composed of strains (RUN 1794 and RUN 1854) of phylotype III and I, respectively, and originating from the localities of Kondoukro and Yamoussoukro, was very virulent. The resistant varieties were for the F1 kalenda eggplant, for the yellow chilli from Burkina and for the F1 Lindo tomato. These varieties could be used in the fight against bacterial wilt in Côte d'Ivoire.
