Food crop of wheat

Wheat was established food crop at the dawn of history. It probably originated from grasses native to the Middle East, but cultivation of bread wheat was common in Europe by the time of the Greek and Roman Empires, and wheat was brought to America by the earliest explorers. It is grown in temperate zones around the world and on some part of every continent except Antarctica.

The principle species of wheat are Triticum vulgae or bread wheat: T.durum, which has extra hard kennels used primarily for macaroni and related pasta products; and T.compactum or club wheat, which has very soft kernels.

These are numerous varieties and cultivars within each species. Wheat is also classified in the United Sates according to whether is hard or soft, white or red, and planted in winter or spring. It is also graded according to such criteria as test weight.

It is also graded according to such criteria as test weight per bushel and content of damaged kernels, foreign materials, and wheat of other classes.
