How it works

The wheat classification process involves assessing the inherent quality characteristics of a new variety, focusing on processing and end use performance.

This process involves comparing new varieties for 30 or more quality parameters with a group of control varieties grown at the same time and place over a minimum of three seasons. Quality characteristics assessed during variety classification are more comprehensive than those possible at the point of receival.

Classification delivers Classes of Australian wheat with distinct quality attributes and processing virtues. By following this process and stringently assessing all Australian wheat varieties, Wheat Quality Australia ensures Australian wheat is of a consistent and appropriate quality.


There are four wheat classification zones in Australia and a classification is valid for one zone only.



Australian wheat is classified into classes with distinct quality attributes and processing virtues.


Control Varieties

All wheat varieties are assessed against control varieties during the classification process. A full set of controls for each class and zone is available here.
