Key Practice: L. maculans, the fungal pathogen that causes blackleg in canola, can produce a mycotoxin called sirodesmin PL, but this study found none of it in Alberta canola samples. Project Title, Lead Researcher: “Evaluation of the toxicity of the secondary metabolites produced by Leptosphaeria maculans,” 2012-14, Xiujie (Susie) Li, Alberta Innovates — Technology Futures...

Key result: Clubroot resistance in Canadian canola varieties relies almost entirely on one source, “Mendel”. This study identified many other genes, found genetic markers for them and then crossed some of them into B. napus lines that could be used for breeding. Canola seed breeders can use the results of this work to broaden and...

Key result: This study looked at various clubroot management techniques and found that using clubroot-resistant varieties plus crop rotations with at least two years between host crops were effective in reducing disease severity and yield loss. Project title, Principal investigator: “Management of clubroot in a dynamic environment” Sheau-Fang Hwang, Alberta Agriculture and Food Funding: Growing...

Key Result: This study found that matching genetic resistance to dominant pathotype groups in a field is possible, but more work is needed to make this practical for long-term cultivar rotations and overall blackleg management. Project title, Principal investigators: “Development of canola cultivar blackleg resistance groups: Feasibility evaluation,” Ralph Lange, Alberta Innovates – Technology Futures...
