View of the Teton Mountain Range from the Idaho side, an agricultural field of canola (rapeseed) in full bloom in Teton Valley. (horizontal) In agriculture, canola is a trademarked quality description of a group of cultivars of rapeseed variants from which low erucic acid rapeseed oil and low glucosinolate meal are obtained. Also known as "LEAR" oil (for Low Erucic Acid Rapeseed), Canola was initially bred in Canada by Keith Downey and Baldur Stefansson in the 1970s...A Bottle of Canola Oil from CanadaOnce considered a specialty crop in Canada, canola has evolved into a major North American cash crop. Canada and the United States produce between 7 and 10 million metric tons (tonnes) of canola seed per year. Annual Canadian exports total 3 to 4 million metric tons of the seed, 700,000 metric tons of canola oil and 1 million metric tons of canola meal. The United States is a net consumer of canola oil. World production of rapeseed oil in the 2002?2003 season was about 14 million metric tons. ..Canola was developed through conventional plant breeding from rapeseed, an oilseed plant with roots in ancient civilization. The word "rape" in rapeseed comes from the Latin word "rapum," meaning turnip. Turnip, rutabaga, cabbage, Brussels sprouts, mustard and many other vegetables are related to the two canola species commonly grown: Brassica napus and Brassica rapa. The negative associations with the word "rape" in North America resulted in the more marketing-friendly name "Canola", but also to distinguish it from regular rapeseed oil, which has much higher erucic acid content...Hundreds of years ago, Asians and Europeans used rapeseed oil in lamps. As time progressed, people employed it as a cooking oil and added it to foods.
