Quality of western Canadian canola 2011
The 2011 total glucosinolate content averaged 10.3 µmoles/g similar to what was observed in 2010 (9.9 µmoles/g) but slightly higher than what was observed in 2009 (9.6 µmoles/g). This constant low total glucosinolate content is a direct result of the constant breeding efforts from the various breeding programs and the very little proportion of Brassica rapa grown in Canada. Since 2006, Brassica napus varieties represented more than 99% of the samples received by the Canadian Grain Commission in its harvest survey program.
The average level of total seed glucosinolates in the December 2011 canola exports was 12.7 µmoles/gof seed, similar to the average of the 2010-11 shipping season. Glucosinolate contents of canola exports for the 2011-2012 shipping season will remain similar to the averages observed during the 2010-2011 shipping season.
