Exploring Brassica oleracea for resistance to the newly emerged Plasmodiophora brassicae pathotypes: Resistance mapping and introgression into canola

The Challenge

New, and more virulent, pathotypes have been recently identified in Canadian canola fields and the identification of resistance to these newly evolved pathotypes and introgression into canola is needed

The Project

Introgress clubroot resistance genes from the cabbage/cauliflower-type plant species (B. oleracea) into Canadian canola and develop molecular markers for these genes.

The Results

Brassica oleracea showed resistance to multiple pathotypes, indicating that there is potential for the development of clubroot resistant canola cultivars that possess more robust and durable resistance to the disease.

Grower Benefits

These results should increase breeding efficacy for the development of clubroot resistant canola cultivars to help reduce the impact of clubroot.
