Rapeseed Viewed from Ashley Hill in UK

Rapeseed (Brassica napus), also known as rape, oilseed rape, rapa, rappi, rapaseed (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). The name derives from the Latin for turnip, rāpa or rāpum, and is first recorded in English at the end of the 14th century. Older writers usually distinguished the turnip and rape by the adjectives round and long(-rooted) respectively.[2] See also Brassica napobrassica, which may be considered a variety of Brassica napus. Some botanists include the closely related Brassica campestris within B. napus. (See Triangle of U). Rapeseed was the third leading source of vegetable oil in the world in 2000. In agriculture, canola is the name given to certain varieties of rapeseed oil, or the oil produced from those varieties. Canola is a trademark for a hybrid variety of rape initially bred in Canada ("canola" being an acronym for Canadian oil, low acid[3]). Rapeseed oil was produced in the 19th century as a source of a lubricant for steam engines. It was less useful as food for animals or humans because it has a bitter taste due to high levels of glucosinolates. Canola has been bred to reduce the amount of glucosinolates, yielding a more palatable oil. This has had the side-effect that the oil contains much less erucic acid.
