Rapeseed (Brassica napus subsp. napus), also known as rape, oilseed rape, and, in the case of one particular group of cultivars, canola, is a bright-yellow flowering member of the family Brassicaceae (mustard or cabbage family), cultivated mainly for its oil-rich seed. It is the third-largest source of vegetable oil and second-largest source of protein meal in the world.
