Wheat is the most important food grain of the temperate zones - both north and south.
World acreage in wheat is estimated at near 500 million with near 60 million acres in the United States. Production in the United States was 1,524,340,000 bushels in 1967. Wheat has been a food crop for mankind since the beginning of agriculture. 6750 B.C. have been found in Iraq, and many other findings in Eastern Mediterranean countries are nearly as old. The Middle East is probably the area of origin, and wheat apparently spread throughout Europe not later than the Stone Age.
