Quality of western Canadian canola 2014

Chlorophyll content

Chlorophyll content averages of producer samples graded Canola, No. 1 Canada were 10, 14 and 14 mg/kg in Manitoba, Saskatchewan and Alberta, respectively. The overall average for Canola, No. 1 Canada was 13 mg/kg, higher than what was observed for the 2013 harvest (12 mg/kg), but significantly lower than the 17 mg/kg and 16 mg/kg observed in 2012 and 2011, respectively. Individual producer samples of Canola, No. 1 Canada from Manitoba, Saskatchewan and Alberta-Peace River had chlorophyll levels ranging from 4 to 35 mg/kg, 4 to 40 mg/kg and 4 to 46 mg/kg, respectively. The mean chlorophyll content varies greatly from year to year due to environmental conditions. Once again, location had an important effect on chlorophyll levels in the analyzed samples. Crop District 6 from Alberta averaged the highest chlorophyll content for samples graded Canola, No. 1 Canada (18 mg/kg). Saskatchewan Crop District 7 and Alberta Crop District 5 also had chlorophyll content averages higher than 16 mg/kg for samples graded Canola, No. 1 Canada.

Chlorophyll levels for Canola, No. 2 Canada samples averaged 33 mg/kg, much higher than what was observed for the 2013 harvest (27 mg/kg) and similar to the average observed in 2012 (35 mg/kg). Samples graded Canola, No. 3 Canada showed an average chlorophyll content of 68 mg/kg, much higher than the record low observed in 2013 (25 mg/kg) and much higher than the 50 mg/kg observed in 2012.

To be graded Canola, No. 1 Canada, samples must contain no more than 2.00% distinctly green seeds. Distinctly green seed averages were 0.56, 0.55 and 0.68% in Manitoba (0.44% in 2013), Saskatchewan (0.38% in 2013) and Alberta-Peace River (0.51% in 2013) for Canola, No. 1 Canada samples, respectively.

Chlorophyll content of Canadian canola exports is affected by distinctly green seeds and dockage content (no more than 2.5% for commercially clean exports). Dockage averages for Canola, No. 1 Canada was 1.81 and 1.71% for commercially clean cargoes for November and August to November 2014 exports, respectively. Dockage was much higher for for the not-commercially clean exports for August to October 2013 (2.92%). Since August 1st, 2014, the distinctly green seed contents for individual cargoes of Canola, No. 1 Canada ranged from 0.4 to 2.0%. Chlorophyll content averages of Canola, No.1 Canada exports ranged from 9 to 29 mg/kg, with commercially clean exports having a lower chlorophyll content than not commercially clean exports.

Up to now chlorophyll content averages were 23 and 15 mg/kg for exports of Canola, No. 1 Canada in November and in the August-to October period, respectively. This is higher than the average obtained for the 2014 harvest (13 mg/kg), with early exports showing lower chlorophyll contents than later exports (14 in September 2014 versus 23 mg/kg in November 2014). These chlorophyll content variations reflected distinctly green seeds average variations observed between harvest samples (0.59%), exports average (0.85%) and month to month variations (0.47% in August versus 1.56% in November). It is expected that higher distinctly green seeds content will lead to higher chlorophyll content in exports.

It is expected that chlorophyll data for the 2014-15 exports will be higher than chlorophyll data reported for the 2014 harvest. It is also expected that export chlorophyll data will be much higer for the 2014-15 shipping season than results observed during the 2013-14 shipping season. It is likely that a signigicant numbers of Canola, No. 1 Canada exports will have chlorophyll contents higher than 25 mg/kg.
