It is cultivated in many countries around the world. It occurs as spring oilseed rape (annual) and winter oilseed rape (biennial plant). Winter oilseed rape is an important part of the crop rotation as it leaves a large amount of organic matter and potassium-rich crop residues. Such sites are suitable for cereal cultivation. The seeds yield edible rapeseed oil, which is the basis for the production of many cooking fats.
