merge with canola? 
Colza and Canola are the same plant. Canola is a registered trade name.
The article shoudl be nerged with something, because the statements are... at least off if not wrong: I clicked the links and it clearly takes me to rapeseed oil in other languages, which then takes me to rapeseed and not "colza". I think both species should be under the same page and the difference explained.
