Project Summary:
Blackleg is the most important disease of canola on a worldwide basis. It is caused by the fungal pathogen Leptosphaeria maculans. There is limited information on the genetics of virulence in this pathogen and its likely impact on the durability of resistance in canola. This research is aimed at understanding the virulence in the pathogen, characterising differential lines for host resistance and developing markers for pathogen virulence. The project identified both vertical and horizontal components of resistance in canola lines tested. The virulence of one of the isolates appeared to be inherited in a way which is consistent with a single gene.
