World trade in wheat is greater than for all other crops combined. Globally, wheat is the leading source of vegetable protein in human food.

Wheat was a key factor enabling the emergence of city-based societies at the start of civilization. It was one of the first crops that could be easily cultivated on a large scale, and its seeds could be stored for long periods in a dry climate. The wheat plant has long, slender leaves, stems that are hollow in most types of wheat plants, and heads that have many kinds of flowers, from 20 to 100. The flowers are grouped together in spikelets.

Each spikelet has two to six flowers. In most spikelets, two or three of the flowers become fertilized, and this makes them produce the grains used for food. All cultivated wheats have more than one normal diploid set of chromosomes. The increases in chromosome sets occurs naturally at a low rate. Because they have more chromosomes, their ears of wheat are larger. All man did was to select the plants with extra fat ears of wheat when they occurred.
