Oilseed rape (Brassica napus L. or Brassica napus subsp. napus, an autonym for rapeseed, or Brassica napus Oil Rape Group) is a yellow-flowered annual plant in the Brassicaceae family, formerly known as Crucifers. It is widely cultivated for the production of edible oil and agrofuel. Along with sunflower andolive, it is one of the three main sources of edible vegetable oil in Europe.
In Canada, spring rapeseed, whose erucic acid content was lowered by genetic selection, was renamed canola. Since then, European varieties have also had their erucic acid content reduced, so rapeseed and canola are almost identical.
Etymology : rapeseed comes from the Dutch koolzaad (literally " cabbage seed").()
