Clarification of sprouted definition in canola

Background

In the 2024-2025 crop year, canola samples showed abnormally high amounts of sprouting to varying degrees. In response to multiple industry inquiries related to the Official Grain Grading Guide definition used to assess sprouted damage in canola, the Canadian Grain Commission clarified the definition for sprouted in canola in September 2024.

Definition

• Sprouted canola is defined as those seeds having a ruptured seed coat in combination with either a sprout that protrudes beyond the normal contour of the seed (seeds 1 and 2) or distinct swelling of the seed (seeds 3 and 4). Seeds having a ruptured seed coat that are otherwise sound (seeds 5 and 6) are only considered sprouted when found in combination with seeds meeting the definition of sprouted (seeds 1, 2, 3 and 4).

Conclusion and next steps

Preliminary test results from the Canadian Grain Commission’s Grain Research Laboratory suggest that canola displaying seed coats that are cracked less than seeds 5 and 6 should not be assessed as sprouted. Not assessing canola with seed coats cracked less than seeds 5 and 6 will significantly reduce the amount of canola assessed as sprouted and the resulting downgrades.

Further research on the impacts of sprouted canola on its end use quality is underway to ensure the grading standards are science-based and appropriate for the grading factor they represent. Once that research has been completed, it will be shared with Standards committees for discussion and possible changes to the existing definition and tolerances may be made.
