Rice: From Ancient Origins to Global Crop

Rice, or Oriza sativa, has been a staple food for over 8000 years, particularly in Asia. It is a diverse crop with thousands of varieties. A 2011 study confirmed that the major subspecies, Japonica and indica, share a common origin. Rice's domestication began in China and India, later spreading to Europe and the Americas. It requires specific irrigation for cultivation and thrives in hot climates. Rice undergoes milling to produce brown and white rice, with white rice being more popular due to its shelf life. Despite its labor-intensive cultivation, rice remains a crucial global food source.
