Research Objective

  • To understand the source of clubroot in Canada since discovery in 2003.
  • To characterize genetic resistance breakdown across Canada

Project Description

Clubroot, caused by Plasmodiophora brassicae, has spread through the Prairies since it was first identified in 2003 and is found in southern Alberta, Saskatchewan, Manitoba, and North Dakota.  This was a two year study to trace back the source of clubroot and study the breakdown of current genetic resistance across the Prairies. The project concluded that the genetic resistance breakdown was similar across Canada. With new pathotypes arising of clubroot, it is important to be able to compare across provinces, which is what this project accomplished by surveying such a diverse range of geographic regions affected by clubroot.
