Scientists work toward new canola varieties as clubroot spreads across the Prairies

Scientists are in a race against a disease that threatens canola, one of Western Canada’s most important crops, and they are looking to the Canadian Light Source to learn more about the genetic resistance to this disease.

Clubroot causes swelling on the canola roots eventually killing the plant. Finding a way for those roots to resist this soil-borne disease is the cornerstone of the strategy for managing the disease, says Gary Peng, a scientist at Agriculture and Agri-Food Canada’s Saskatoon Research and Development Centre.

“The consequences of clubroot in a canola field can be devastating. It can wipe out the whole crop,” said Peng.

The first case of clubroot in canola was reported in 2003 in several fields in the Edmonton area. The infestation spread rapidly to fields north of the city and the disease is now found in more than 2,000 fields in a wide band across Alberta. In Saskatchewan, it was first detected in 2008, but significant evidence of the disease attacking the roots of canola plants wasn’t identified until 2011, according to the Canola Council of Canada.
