Canola Disease Resistance Ratings

This publication provides disease ratings for registered varieties of canola. Resistance to diseases can be an important consideration in the selection of an appropriate variety, but there are many other agronomic factors to consider as well. Not all of the varieties listed will be suitable for every region of British Columbia.

Canola Blackleg

The resistance ratings of some of the canola products may be lowered if they are infected with new, more aggressive strains of the blackleg fungus. Very little information is available on blackleg disease reaction of canola products to new strains. All B.rapa (Polish) cultivars are susceptible to blackleg.

Canola White Rust/Staghead

  Resistant Intermediate Susceptible
Polish
Brassica rapa (= B. campestris)		 None None All cultivars are susceptible to the prevalent pathotype (7V)
Argentine
B. napus		 All cultivars None None

Canola - Alternaria

There are currently no canola varieties that are resistant to Alternaria stem and pod spot. However, Brassica rapa (= B. campestris) cultivars are much more susceptible than B. napus cultivars.
