DefendR Genetic Traits

The DefendR symbol indicates above industry average levels of genetic resistance to one or more of the most important canola yield reducing factors. It represents the strength of the breeding programs of our primary canola breeding partners and a promise to canola growers that they are purchasing a variety that has exceptional yield potential and leading genetics for disease and/or harvest management.

Pod DefendR

The pod DefendR trait means outstanding genetic resistance to pod shattering in BrettYoung canola hybrids.

The introduction of pod shatter-resistant hybrids to canola growers several years ago led to a significant increase in adoption of both direct harvesting and delayed swathing of canola crops.
BrettYoung canola growers can now enjoy this same flexibility because of our new pod shatter-resistance trait, which is non-GMO, and delivers dependable levels of shattering tolerance.


Sclerotinia DefendR

For growers looking to reduce the impact of this disease, BrettYoung’s DefendR Sclerotinia tolerance trait is included in both the 6074 RR and 6076 CR hybrids. Screening and testing results in both these varieties have shown improved tolerance superior to susceptible checks in reaction to inoculation with Sclerotinia sclerotorium using industry-approved standardized testing protocol.

The DefendR trait in 6074 RR and 6076 CR provides Sclerotinia tolerance at levels that will

  • Reduce the impacts of infection and reduce yield loss wherever disease pressure is present.
  • Allow for greater flexibility in fungicide application timing when flowering is uneven and staggered, which otherwise makes fungicide application timing difficult.
  • Reduce the impact of Sclerotinia in long-flowering crops where the window of fungicide protection has lapsed.

Blackleg DefendR 

Blackleg is back in the spotlight as a disease that is evolving and making a strong resurgence in intensive canola production areas. Most agree that managing this disease requires a combination of rotation, crop management (including regular field scouting) and proper variety selection as important factors to reducing the impact of this disease.

The DefendR Blackleg trait means the BrettYoung canola variety is rated as a strong R for Blackleg resistance. It also means that the variety incorporates multiple major genes to defend against multiple strains of Blackleg. DefendR Blackleg varieties achieve a broader level of resistance compared to competitive R-rated varieties that have either no, or only one, major gene for Blackleg resistance.

Clubroot DefendR 

Previously considered primarily a Central Alberta issue, Clubroot has now been identified in all three Prairie provinces. In 2013, a new Clubroot pathotype was identified in Alberta as the canola varieties up to that time thought to be Clubroot resistant were showing high levels of infection. New pathotypes have since been identified in several areas.

The DefendR Clubroot trait is resistant to pathotypes 2, 3, 5, 6, 8, 3H, 3A and 5X. BrettYoung will continue to commercialize DefendR-rated Clubroot resistant genetics couplied to high yielding, high performance varieties.

Harvest Timing

Posted: Aug 16, 2022

If you don’t already have crops being harvested, you’re likely keeping a close eye on your fields to decide when to start. Just like any other crop, timing of when you start harvesting your canola can have big impacts on yield and quality, here are a few things to keep in mind as you watch your crops progress this fall.

The first decision to make is whether you will be harvesting or swathing a crop. This is largely influenced by hybrid– if you have seeded canola with pod shatter protection, such as a Pod DefendR hybrid, you may be able to leave these fields out to straight cut.

Scouting For Blackleg in Canola

Posted: Aug 16, 2022

Disease surveying in the fall is one of those tasks many of us drag our feet on. Nothing can be done that late in the season to protect the crop from damage, so why survey? The value of surveying is to assess your current management practices and hybrid selections to help make better-informed decisions that will maximize yield potential in future years.

For a disease like blackleg, the canola crop may not show visible signs of damage. Only after disease surveying may the true level of blackleg damage be determined, along with the bushels lost to the disease.
