Grown.

Economic significance. Var. Oleifera DC. oleaginous plant is important for many northern countries of the northern hemisphere, but in Bulgaria is replaced entirely with sunflowers. Honey plant. May serve to feed the big livestock. Var. rapifera Metzg. limited cultivated as root-crop vegetable and fodder plant. It grows well only under irrigation.

Note. For our country given only as a cultivated plant. Its oilseed form, however, is collected as outcast since 1885.

Rapeseed (Brassica napus), also known as rape,[1] oilseed rape,[1] 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), (油菜: 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.[2] 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.[3]

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),[1] which attributes the names to other sources:
