Historical protein content for Canada Western Red Spring wheat by crop region

This report presents historical data on protein content for Canada Western Red Spring (CWRS) wheat grown since 1995. Wheat samples were submitted to the Canadian Grain Commission’s Harvest Sample Program by producers. Quality data is compiled from the results of analytical tests performed in the Grain Research Laboratory.

Data features and interpretation

These data (Figure 1) represent all CWRS wheat samples received by the Harvest Sample Program since 1995 and include all grades. Results with protein content outside the typical expected range (above 20%) are not included. The box and whisker plots show the distribution of protein content in a given crop region (Figure 2) and year. The shaded boxes represent the middle 50% of the data, with the horizontal line indicating the median value. The vertical lines (whiskers) represent the bottom and top 25% of values, respectively. Mean value is represented by a white circle. All registered CWRS varieties have the potential for high protein. Variation between crop regions and years is primarily related to growing conditions.
