Rapeseed (Brassica napus) is a vital flowering plant, prized for its oil-rich seeds. Cultivated in temperate climates, rapeseed yields canola oil, known for its low saturated fat and high nutritional value. Its bright yellow flowers and distinctive features categorize it into winter and spring varieties. Beyond oil extraction, rapeseed meal serves as nutritious livestock feed. The plant’s versatility extends to biodiesel production, contributing to sustainable energy. Rapeseed cultivation enhances soil quality, combating erosion, and genetically modified varieties offer pest resistance. While “rapeseed” remains in use, “canola” typically denotes low-erucic acid cultivars, emphasizing its adaptability for human consumption in diverse industries.
