The aim of this study was to examine the reaction of different tomato cultivars towards race 1 of Fusarium oxysporum f. sp. lycopersici. The researched tomato cultivars were: Adonis, Gružanski zlatni, Jasmin crveni, Narvik SPF and SP109, breeding lines Hom-3, Hom-4, L-4, S-49, S-31, S- 35, SPA, SPR,V-100, 34/56, 93/10 and 93/16. Reaction to pathogen were tested in F1 generation, as well, in combination of 93/16 x V-100, S-35 x L- 4, S-49 x SPA, 34/56 x SPR, S-49 x Hom-4, 93/16 x Hom-3 and 93/10 x S- 31. Plants were inoculated by submerging wounded roots in to pathogen suspension. Disease was assessed 30 days after inoculation. After evaluation 15 cultivars expressed resistance toward this pathogen. Among them 93/10 x S-31, Hom-3 and 93/10 had average disease rating 1,0. Other genotypes had average disease ratings as follows: Narvik SPF and S-49 (1,1), 34/56, Hom-4 and S-49 x Hom-4 (1,2), while Adonis, 93/16 x Hom-3, 34/56 x SPR and 93/16 x V-100 had average disease rating 1,3. Cultivars SPR and 93/16 had 1,7 ADR, meanwhile Sp-109 had 1,8 average rating. Genotypes SPA (2,1), S-49 x SPA (2,1), V-100 (2,2) and L-4 (2,6) belong to the group of tolerant genotypes who did not expressed typical symptoms of chlorosis and wilt of plant but expressed some level of necrosis of xylem in lower part of plants. Most sensitive to fusarium wilt were S-35 x L-4 (3,3), S-35 (3,5), S-31 (3,6), Gružanski zlatni (3,8) and Jasmin Crveni with average disease rating of 4,0. Cilj ovog rada je da se ispita reakcija različitih kultivara paradajza u odnosu na rasu 1 Fusarium oxysporum f. sp. lycopersici. Ispitivani genotipovi paradajza su sorte: Adonis, Gružanski zlatni, Jasmin crveni, Narvik SPF i Sp-109, selekcione linije Hom-3, Hom-4, L-4, S-49, S-31, S-35, SPA, SPR, V-100, 34/56, 93/10 i 93/16. Takođe, ispitana je i reakcija F1 generacije sledećih kombinacija 93/16 x V-100, S- 35 x L-4, S-49 x SPA, 34/56 x SPR, S-49 x Hom-4, 93/16 x Hom-3 i 93/10 x S-31. Biljke su inokulisane potapanjem povređenog korena u suspenziju patogena. ...
