Brassica napus (Rapeseed)

Synonyms: Brassica rugosa

Wikipedia Abstract

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), consumed in China (油菜籽: Mandarin Pinyin yóucài; Cantonese:yau choy) 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. rapa within B. napus.

Usage [2]  The seed contains up to 45% of an edible semi-drying oil, it is used as a luminant, lubricant, in soap making etc; Rapeseed oil has potential market in detergent lubrication oils, emulsifying agents, polyamide fibres, and resins, and as a vegetable wax substitute. According to the Chemical Marketing Reporter (April 26, 1982) "the most common use for the oil is still in the production or erucic acid, a fatty acid used in turn in the manufacture of other chemicals; The seed husks are used in plastering house walls; A good green manure, the deep taproot improves drainage and loosens heavy soils;
