Canola (Brassica napus) is a genetically altered and improved version of rapeseed that was developed for its superior edible oil and high value meal. The term "canola" can only be applied to those varieties that produce less than 2 percent erucic acid. Canola oil is lower in saturated fats than any other vegetable oil, making it a popular choice among health-conscious consumers. The portion of the seed left after the oil is extracted (canola meal) is of value as feed for livestock and poultry. Canola may also be used as an annual forage. In addition, canola is being considered as a source of biodiesel fuel.
