Sclerotinia sclerotiorim is a facultative parasite that can cause diseases on more than 400 plant species. Sclerotinia wilt presence was observed in Vojvodina during the period 2007-2009 at seven sites (Bečej, Kikinda, Kula, Pančevo, Sombor, Vršac and Zrenjanin). Assessment was done on 8 hybrids (Baća, Bačvanin, Branko, Duško, NS-H-111, Sremac, Šumadinac and Velja). Disease intensity was calculated according to McKinney’s formula. AMMI analysis was used in order to estimate stability of hybrid tolerance to Sclerotinia wilt in different environments. Average Sclerotinia wilt occurrence on sunflower was the lowest in 2007 and the highest in 2009. Sclerotinia wilt was not observed in Zrenjanin and Vršac in 2007, nor in Pančevo in 2008. The lowest average Sclerotinia wilt occurrence during 3-year period was in Sombor and Pančevo. Hybrids Duško, NS-H-111, Sremac and Velja can be recommended for future growing on sites where Sclerotinia wilt of sunflower occurs.
