Using SNP Markers to Assess Genetic Variability of Plasmodiophora brassicae in Canada

Researcher: Bruce Gossen, F. Yu, Agriculture and Agri-Food Canada, Saskatoon SK, M. R. McDonald, University of Guelph, S.E. Strelkov, University of Alberta

Project Code: CARP-CCC 2015-15

Final Report: April 2018

Summary: Clubroot caused by Plasmodiophora brassicae has spread across central Alberta and to isolated fields in southern Alberta, Saskatchewan, Manitoba and North Dakota since it was first identified on canola in 2003. Researchers conducted a two-year project to attempt to trace the dispersal of the pathogen back to its source. In the study, researchers identified breakdown of genetic resistance to clubroot in canola outside of Alberta, and demonstrated that a similar breakdown is occurring wherever canola is grown in Canada, e.g., ON, QC, and even PEI. These studies will permit comparison of the genetic similarity among new pathotypes from widely different geographic locations.
