Experimental grades of wheat and barley – Chapter 24
Official Grain Grading Guide



Criteria for designation as experimental grades

Experimental grades for selected varieties of wheat and barley have been established to allow the Canadian Wheat Board to market test varieties that do not readily fit into the existing grade structure, but which show some promise for acceptablility in world markets.

A variety is eligible to be assigned to the grades defined in the experimental grade schedules only if the variety is designated by one of

  • Agriculture and Agri-Food Canada
  • Canadian Wheat Board
  • Canadian Grain Commission

The criteria for a variety to be eligible for designation are

  • There is evidence that Canadian producers will derive a benefit from its production either immediately or in the future.
  • There is supportive data for its agronomic characteristics and end-use quality.
  • The variety will be produced under contract to the Canadian Wheat Board.
  • The variety will remain in the program for a specified period.

When a variety is no longer eligible for the experimental grades, the Canadian Wheat Board purchases and disposes of all existing stocks to prevent adulteration of registered varieties, unless the Canadian Grain Commission establishes a grade schedule for that variety and any other varieties of that grain having similar qualities.
