Oilseed Crops
We test canola, flax, and sunflower across multi-site, multi-year trials—tracking yield, oil/protein, maturity, standability, and key diseases—to deliver independent, Manitoba-wide comparisons and clear metrics for confident selection.
Variety Description Key
A “CHECK CHARACTERISTICS” is at the bottom of each table for soybean and sunflower to display the long-term yield, number of site years, maturity and any other check attributes.
The grey box has been placed at the bottom of each table for canola and flax displaying the “GRAND MEAN” for Yield (bu/acre) and the corresponding LSD value (p <0.05).
Except for the long-term average yield, variety description information was obtained from the Cooperative Registration Trials. For Relative Maturity, actual number of days will depend on local climactic conditions and to some extent on management practices.
“Resistance Level” ratings: HS = highly susceptible; S = susceptible; MS = moderately susceptible; MR = moderately resistant; R = resistant; ‘-‘ = not available.
Site Years Tested is the cumulative number of locations over the years that a variety has been tested against the check variety.
Indicates a variety that is protected by Plant Breeders’ Rights legislation that complies with UPOV 1978.
Indicates a variety that is protected by, or has been applied for and is pending, Plant Breeders’ Rights legislation that complies with UPOV 1991.
Key to 2025 Yield and Protein Tables
CV % = Coefficient of Variation. A measure of random variation in a trial. A low CV is desirable.
LSD = Least Significant Difference. Varieties must differ by the LSD to be considered significantly different from one another.
Sign Diff = Significant Difference. Indicates if a real difference exists between varieties at an individual site.
