Generating blackleg resistance groups

The Blackleg Management Guide not only provides blackleg resistance ratings but also blackleg resistance groups for current canola cultivars. But how do researchers determine these? Steve Marcroft talked us through how researchers establish resistance groups for canola cultivars, and more importantly, why you should know the resistance groups of the cultivars you grow to manage the blackleg population on your farm.

Blackleg resistance groups for current canola cultivars are available in the Blackleg Management Guide or better yet embedded in The BlacklegCM App.
