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), (: Mandarin Pinyin ''yóucài''; Cantonese:''yau choy'') consumed in China and Southern Africa as a vegetable. 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. Rutabagas, ''Brassica napobrassica'', are sometimes considered a variety of ''B. napus''. Some botanists also include the closely related ''B. campestris'' within ''B. napus''. ''B. napus'' is cultivated mainly for its oil-rich seed, the third-largest source of vegetable oil in the world. == Common names == Rapeseed is known by many common names in the English language. Some names have only been applied to certain subspecies (subsp.), forms (f.), or varieties (var.) of ''B. napus''. ''B. napus'' = ''B. napus'' subsp. ''napus'' = ''B. napus'' subsp. ''napus'' f. ''napus''. This list is from the Germplasm Resources Information Network (GRIN),〔 which attributes the names to other sources: * ''Brassica napus'' – rape * * ''B. napus'' subsp. ''napus'' – Argentine canola, canola, colza, oilseed rape, and rape * * * ''B. napus'' subsp. ''napus'' f. ''annua'' – annual rape and summer rape (treated as ''B. napus'' var. ''annua'') * * * ''B. napus'' subsp. ''napus'' f. ''napus'' – swede rape (treated as ''B. napus'' var. ''biennis'') * * ''B. napus'' subsp. ''napus'' var. ''pabularia'' – Hanover-salad, rape kale, and Siberian kale * * ''B. napus'' subsp. ''rapifera'' – rutabaga, swede (treated as ''B. napus'' var. ''napobrassica''), Swedish turnip (treated as ''B. napus'' Napobrassica Group), and winter rape 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「rapeseed」の詳細全文を読む スポンサード リンク
