The domestication of rice dates to about 4000 b.c. Wheat and barley are two of the founder crops of the agricultural revolution that took place 10,000 years ago in the Fertile Crescent and both crops remain among the world's most important crops. dicoccoides, or T. dicocoides) is a plant of the genus Triticeae and the genus Triticeae, generally self-pollinating, grown in winter and harvested in summer. According to botanist Agathe Roucou and colleagues, the domestication process indirectly caused multiple changes in the plant.

Therefore, the synthetic lines are typically crossed to an adapted wheat cultivar, then backcrossed once or twice to the adapted cultivar, followed by selection. II. Figure 3. 2007. Exploring and exploiting cuticle biosynthesis for abiotic and biotic stress tolerance in wheat and barley. Today, it grows along the Near Eastern Fertile Crescent in countries such as Israel, Jordan, Syria, Lebanon, eastern Turkey, western Iran, and northern Iraq. The D genome provided wheat with adaptability to the harsh environmental conditions of Central Asia, as well as proteins that improved the breadmaking properties of the flour. The evidence is abundant that by about 10,400 years ago, domesticated wheat was in widespread use throughout the Levant region; but when that started is up for debate.

Most of the 25,000 different forms of modern wheat are varieties of two broad groups, called common wheat and durum wheat. In domesticated wheat this dispersal mechanism has been lost; the ear remains entire even after ripening, making it easier for the grains to be gathered.

Other surveys at Bouldnor Cliff identified a submerged Mesolithic site 16 meters below sea level. Triticum spp. Wheat was domesticated ten thousand years ago in the present-day Middle East, when humans rapidly modified the crop's key traits. Another possible method is that the early farmers harvested wheat that was ripe but not yet self-pollinated, thus harvesting the wheat that was still on the plant. doi: 10.7554/eLife.78526. Wheat domestication involves a limited number of chromosome regions, or domestication syndrome factors, though many relevant quantitative trait loci have been detected. The chromosome number of this plant is then doubled by treating with colchicine to produce AABBDD plants, the same as common wheat. Most of the 25,000 different varieties of todays wheat fall into two broad groups called bread wheat and durum wheat. The diversity present across the vast range of Ae.

The availability of reference genomes for wheat and some of its progenitors, as well as for barley, sets the stage for answering unresolved questions in domestication genomics of wheat and barley.

According to French botanist Agathe Roucou and colleagues, the domestication process also caused multiple changes in the plant that were generated indirectly. This was elegantly demonstrated by John Bennet Lawes in the 1880s when he decided to allow part of the famous long-term Broadbalk experiment at Rothamsted to return to its natural state ().He therefore left part of the wheat crop unharvested in 1882 and .
