Resumo: | Fusarium wilt, caused by three races of Fusarium oxysporum f. sp. lycopersici, is one of the most important diseases of tomato (Lycopersicon esculentum). Races 1 and 2 are distributed worldwide whereas race 3 has a more limited geographic distribution with no report thus far in Brazil. Seven F. oxysporum isolates were obtained from wilted tomato plants of race 1 and 2-resistant hybrids 'Carmen' and 'Alambra' in Venda Nova do Imigrante (State of Espírito Santo), Brazil. Virulence assays were performed using a set of the race differential cultivars: 'Ponderosa' (susceptible to all races), 'IPA-5' (resistant to race 1), 'Floradade' (resistant to races 1 and 2) and 'BHRS-2,3' (resistant to race 3). All isolates were highly virulent to 'Ponderosa', 'IPA-5' and 'Floradade' and were able to infect only a few plants of 'BHRS-2,3'. An additional virulence test was conducted including the same set of cultivars plus Lycopersicon pennellii 'LA 716'. Identical results were obtained with L. pennellii displaying an extreme (immune-like) resistant response. These results indicated that all seven isolates could be classified as F. oxysporum f. sp. lycopersici race 3. This new Fusarium wilt might became an economically important disease since race 3-resistant cultivars adapted to Brazil are not yet available. |

An additional virulence test was conducted including the same set of cultivars plus Lycopersicon pennellii 'LA 716'. Identical results were obtained with L. pennellii displaying an extreme (immune-like) resistant response. These results indicated that all seven isolates could be classified as F. oxysporum f. sp. lycopersici race 3.
