Wheat: Classes and varieties
Classes
Canadian wheat varieties are grouped into classes by their functional characteristics. Canadian wheat classes are categorized as western Canadian or eastern Canadian by the regions in which the varieties are grown.
Canada Eastern Other Wheat
The selection of CEOW wheat varieties is the responsibility of the receiving elevator. Each individual company has their own selection criteria and specifications. All CEOW selected will be graded according to the specifications listed in the Wheat CE Other Wheat primary grade determination table.
In eastern Canada, varieties of wheat that are neither assigned to a class for the region, nor selected as CEOW are eligible for the class Canada Eastern Feed (CEFD).
