Resumo
Vascular wilting in tomato plants is an important
disease caused by soil-inhabiting pathogens, especially
Verticillium dahliae, which results in significant production
losses. Control measures against this disease are difficult to
implement due to intrinsic pathogen characteristics, such
as high adaptability to the subterranean environment, in
association with the host, and development of resistance
structures that remain viable in the soil for long periods. The
introgression of genes that express resistance is the main
control measure and requires a continuous characterization
program of resistant accessions. This study aimed at
identifying tomato (Solanum lycopersicum) accessions
resistant to V. dahlia, by using the phenotypic and genotypic
methods. The reaction of 33 tomato accessions to different
V. dahliae isolates was reinforced by molecular analysis,
through markers linked to Ve resistance genes. The
combination of bioassays and specific molecular markers
showed a high correlation (94.3 %), with the selection of 25
accessions resistant to V. dahliae.
