This project is still in progress, but aims to simplify the identification of Brassica napus canola lines with tolerance to sclerotinia stem rot.
This project will attempt to simplify the identification of Brassica napus canola lines with tolerance to sclerotinia stem rot. Researchers will characterize substances produced by the fungus that cause the characteristic brown, necrotic (dead) lesions on the plant or which compromise the ability of the plant to defend itself against attack by the fungus. These substances will be used to identify B. napus lines from collections at plant genetic resource centres to find those that are most tolerant or resistant to individual substances. Combining the resistance traits through traditional breeding will accelerate the development of canola varieties with better tolerance or resistance to stem rot.
