Introgression of clubroot resistance from B. rapa to B. napus canola and identification of molecular markers for resistance, and pyramiding of this resistance with other resistance genes

The Challenge

Extensive use of the same clubroot resistant canola cultivars can lead to the breakdown of current genetic resistance. To combat this, it is important to have cultivars that have multiple resistance genes.

The Project

Introgress clubroot resistance from Brassica rapa to canola. The B. rapa germplasm used in this research carries resistance to pathotypes 3 and 3A. This resistance is not strongly associated with the two well-known sources of CR, meaning it could be a new source of resistance.

The Results

Grower Benefits

New sources of clubroot resistance will help to avoid breakdown of genetic resistance, giving growers better clubroot control without compromising yield.
