2021 Canola Regional Variety Trials

The Canola Performance Trials (CPT) results in this report are based on 12 standard or swathed trials and 15 straight cut small plot trials across the Prairies. Site distribution is based on seeded acres in Manitoba, Saskatchewan and Alberta.

Drought conditions and early season insect pressure proved to be incredibly challenging and contributed to a lower number of successful trial sites. For more information on accumulated precipitation, visit Agriculture and Agri-Food Canada’s website.

The small plot system ensures that:

  • All varieties are treated with appropriate commercially associated herbicides: LibertyLink, Roundup Ready, TruFlex and *Clearfield. *only in Manitoba
  • All varieties are treated with appropriate commercially associated seed treatments.
  • An independent third-party representative inspects all trials.

The CPT Technical Committee has established protocols and developed research plot designs to ensure the data is representative. Performance objectives were established to provide guidelines on timely field operations and data collection. All sites are inspected to verify these guidelines were followed to allow a fair comparison among the varieties tested.

The 2021 program was funded by Alberta Canola Producers Commission (Alberta Canola), Saskatchewan Canola Development Commission (SaskCanola) and the Manitoba Canola Growers Association. The 2021 trials were coordinated by Murphy et al Inc. with the direction from the CPT governance and technical committees. The Manitoba Canola Growers Association administered the program with additional support from Alberta Canola, SaskCanola and the Canola Council of Canada.

Commercial canola varieties tested in the 2021 small plot trials had seed provided by BASF – InVigor, BrettYoung Seeds, Corteva-Brevant, Canterra Seeds, Bayer-DeKalb, Corteva-Pioneer, Nutrien-Proven Seeds, Corteva-Brevant/Pioneer and Winfield United-Croplan.

Results are organized by short, medium, and long season zones. CPT uses the Western Canada Canola/Rapeseed Recommending Committee season zones, which are based on typical frost-free days, growing degree days and soil type. See the map for reference.

The results tables include yield, days to maturity and lodging scores for each variety. Lodging scores are between one and five, with one being no lodging and five being completely lodged. It wasn’t required by site cooperators to record height values, so they were not provided.

Gross revenue is the yield multiplied by $20.27/bu. This is based on the October 2021 futures price of $893.60 per tonne opening price on Oct. 7, 2021, and standard (50-pound) bushel weight. No basis or other deductions were taken off the futures price.

This report is one of several sources of information to consider in making the best decisions for your farm.

Seed is a major input decision that every grower has to make. In addition to evaluating data from sites near your farm, consider several years of data (at from small plot and field scale sites grown in a range of agronomic and environmental conditions across Western Canada to make a well-informed choice. Consider climatic factors, geographic factors, herbicide tolerance systems, disease management, agronomic or special traits and yield potential for your operation when looking at days to maturity, lodging scores, disease tolerance and yield values of the varieties included in this booklet. Use caution when basing hybrid performance off a single site or single- year average yield. Compare varieties over multiple years to better understand performance under different environmental conditions.
