Quality of western Canadian canola 2016 - Harvest sample program samples and grade distribution

Harvest sample program samples and grade distribution

This report of quality data for the 2016 harvest is based on analyses of 1,915 individual canola samples. Composites of various grades from various crop districts composites from each province were made using these samples.  Specialty oil samples, such as high oleic acid, low linolenic acid, and high erucic acid, were excluded from this report.  Slightly less canola samples were received in 2016 when compared to the 2015 harvest (1941 samples) but more samples were received when compared to the 5-year average (1885 samples).

The composition of 2016 samples was compared to 2015 results and to long-term sample program means (Table 1). Comparison with the quality of Canadian canola exports shipments is provided in Table 6 and Figure 6.

In 2016, 95.4% of the samples were graded Canola, No. 1 Canada, compared to 91.5 in 2015 and 80.8% in 2014 (Figure 5). This is much higher than the 5-year average of percentage of Canola, No. 1 Canada (86.6%). The grade distribution of the 2016 canola crop varied slightly between crop districts, but differences were less than what was found  the previous year. The lowest percent of samples graded Canola, No. 1 Canada was found in the crop district 6 of Manitoba (90.2 %).

The main degrading factor for Canola, No. 1 to Canola, No. 2 was distinctly green seed counts.  Distinctly green seed counts (DGR) were 0.47% in Canola, No. 1 Canada, 2.25% in Canola, No. 2 Canada, 2.21% in Canola, No. 3 Canada and 1.66% in Sample.  Most of samples with grades lower than Canola No. 2 were downgraded because of admixtures and sprouting, not because of Distinctly green counts. The Official Grain Grading Guide defines conspicuous admixture as material found in the sample after cleaning and is easily distinguished from canola without the use of magnification.
