Wheat includes any agricultural cereal grass of the genus Triticum in the grass family Poaceae. Wheat is one of the top three cereal crops in terms of global production, along with maize and rice; together wheat, maize, and rice provide over half of the global requirement of calories and protein (Biodiversity International 2007). Wheat can grow in a wide range of climates; though, it grows most favorably in temperate climates and is susceptible to disease in very hot and humid zones.
