Resumo: Fusarium oxysporum f. sp. vasinfectum (FOV) is one the most destructive okra (Abelmoschus esculentus) pathogens in Brazil. Fifty-four okra accessions were evaluated for resistance to FOV. Greenhouse screening was initially carried out with one FOV isolate ('Fus-194'). Inoculation (in all assays) was carried out with 21-day-old plantlets, using the root-dipping inoculation technique. Thirty-three accessions displaying differential responses in the first screening were re-evaluated in two additional assays, using two FOV isolates ('Fus-194' and 'Fus-201'). Twelve accessions were rated as highly to intermediately resistant to 'Fus-194' during the dry/moderate temperature season, whereas nine accessions were classified as highly to intermediately resistant to 'Fus-201'. In the assay carried out in the wet and warm season, 72% of the accessions were classified as having high and intermediate resistance to 'Fus-194', and 32% were resistant to 'Fus-201'. The accessions 'Santa Cruz-47', 'BR-2399' and 'BR-1449' were the most promising resistance sources.
