Wheat seeds, crumbs, and pollen were not found at Bouldnor Cliff, but DNA sequences from the sediment match Near Eastern wheat, which is genetically different from the LBK forms. 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. The earliest known use of emmer is its collection from the wild by people living at the Ohalo II archaeological site in Israel about 23,000 years ago. Science. Wheats D genome ancestor is the goatgrass Aegilops tauschii, which occurs across a broad range of the Middle East and Asia from Syria to China. Figure 4. Photo credit: Pat Byrne.

The main difference between wild forms and domesticated wheat is; domesticated wheat has larger grains with rind and semi-brittle stems. The International Maize and Wheat Improvement Center (CIMMYT) has been a leader in producing and utilizing synthetic hexaploids, with over 1,500 synthetics developed (Mujeeb-Kazi and Hettel, 1995; Rosyara et al., 2019). Since then, improvement in various traits including resistance to diseases, insect pests, saline and drought stresses, grain yield, and quality were improved through selections by early farmers and then planned hybridization after the discovery of Mendel's laws.

In: Soltis D, Soltis P (eds) Isozymes in Plant Biology. Some scholars argue for a fairly rapid process, of a few centuries; while others argue that the process from cultivation to domestication took up to 5,000 years. Crop Wild Relatives in Genebanks. Part of wheats adaptability is due to the fact that it occurs both as winter habit varieties (requiring a cold period of 6 to 8 weeks to trigger reproduction), and spring habit varieties (not requiring the cold period). 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. Utilizing wild grass biodiversity in wheat improvement: 15 years of wide cross research at CIMMYT. 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 .
