Verticillium longisporum is a soil born vascular fungal pathogen on Brassicas oil crops (Heale et al. 1999). Due to the high demand for rapeseed oil, the area under oilseed rape cultivation continues to rise dramatically (Eynck et al 2008). The current European cultivars posses a low level of resistance for this disease, so a severe infection can produce major yield losses. The aim of this study was to identify some oilseed rape cultivars with resistance to Verticillium longisporum. For this purpose we tested a number of 39 cultivars of oilseed rape to Verticillium longisporum by artificial infection. The experiments were conducted in the climatic chamber under controlled condition. Ten-day seedlings were artificial infected with the pathogen by root deep inoculation. The winter oilseed rape varieties Express (less susceptible) and Falcon (highly susceptible) were used as reference controls in our experiment. In order to determine the most resistance cultivars, for each accession was calculated area under disease progress curve (AUDPC).
