| Summary: | Aim of this study is to determine the impact of race 3 of fusarium wilt on some tomato cultivars if it occurs in Serbia. For this purpose eleven tomato cultivars were inoculated with this pathogen: 129 - sprin, Balkan F1, Danubius F1, Jasmin crveni, M - 7, M - 10, Marko F1, Nada F1, Narvik, Šampion F1, Zlatni Jubilej F1 by applying classic method of inoculation by submersing the injured root in fungi suspension. Disease was assessed 30 days after inoculation using an ordinal scale range from 1 - 5. After assessment, Nada F1 and 129-Sprin had lowest average disease rating (2,9), and marked as tolerant. All the other cultivars were consider susceptible with ADR values higher than 3,0 in the following order: Narvik (3,6), Šampion F1 (3,8), M-7 (3,9), Z. Jubilej F1 (4,1), C. Jasmin (4,2), Danubius F1 (4,4), Balkan F1 (4,5), Marko F1 and M-10 (4,6). Based on these results we can conclude that if the race 3 of Fusarium oxysporum f. sp. lycopersici occur in Serbia it could seriously jeopardize tomato production.
