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. Cilj ovog istraživanja je da se utvrdi kakav bi bio uticaj rase 3 fuzarioznog uvenuća paradajza na pojedine kultivare ukoliko bi se ova rasa pojavila u Srbiji. U te svrhe inokulisano je jedanaest kultivara ovim patogenom i to: 129 - sprin, Balkan F1, Danubius F1, Jasmin crveni, M - 7, M - 10, Marko F1, Nada F1, Narvik, Šampion F1, Zlatni Jubilej F1, primenom klasične metode inokulacije umakanjem povređenog korena u suspenziju gljiva. Nakon 30 dana rađena je procena pojave oboljenja upotrebom skale od 1 - 5. Nakon evaluacije, Nada F1 i 129-Sprin su imali najnižu vrednost ADR-a (prosečni nivo oboljenja) (2,9), i obeleženi su kao tolerantni. Svi ostali kultivari smatrani su osetljivim sa vrednostima ADR višim od 3,0, po sledećem rasporedu: 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). Na osnovu ovih rezultata možemo zaključiti da ako bi se rasa 3 Fusarium oxysporum f. sp. lycopersici pojavila u Srbiji mogla bi ...
