Wheat was one of the first crops to be domesticated more than 10,000 years ago in the Middle East. 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. Wild wheat shatters and falls to the ground to reseed itself when ripe, but domesticated wheat stays on the stem for easier harvesting. Their improved yield performance under drought stress conditions appears to be due at least in part to shifts in their rooting profile, whereby a greater proportion of root biomass is produced deeper in the profile (Lopes and Reynolds, 2011; Reynolds et al., 2008). Modern wheat cultivars also have a shallower root system, with a larger proportion of fine roots, investing biomass above rather than below ground.

When wild wheat ripens, the stems, the part that holds the wheat stems together, break down so that the seeds can self-pollinate and sprout faster without the husk. Formed partly by migratory farmers and partly by local hunter-gatherers adapting new technologies, the Lindearbandkeramik (LBK) culture is often associated with the importation of wheat and other crops from Asia to Europe. This wild species was domesticated to form emmer wheat (Triticum turgidum ssp. The major factor underlying human civilization is domestication of plants and animals. A creative strategy for addressing the impoverished D genome diversity of common wheat is the development of synthetic hexaploid wheats (McFadden and Sears, 1946; Trethowan and Mujeeb-Kazi, 2008; Ogbonnaya et al., 2013).

Science. Scholars suggest that the wheat got to Britain by boat. Germplasm released by the Centerincludes breeding lines for disease and insect resistance, bread making quality, and other traits. Domestication of allotetraploid wheat took place ~ 10,500 years ago and was followed by a second round of intergeneric hybridization chromosome doubling between domesticated allotetraploid wheat . 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. https://doi.org/10.1007/s11032-011-9608-4. PLoS Biol 6(6):e148. Hybridization between these progenitors less than one million years ago (Marcussen et al., 2014) gave rise to the tetraploid species Triticum turgidum ssp. Figure 2.
