The earliest evidence for both domesticated einkorn and emmer wheat found to date was at the Syrian site of Abu Hureyra, in occupation layers dated to the Late Epi-paleolithic period, the beginning of the Younger Dryas, ca 13,00012,000 cal BP; some scholars have argued, however, that the evidence does not show deliberate cultivation at this time, although it does indicate a broadening of the diet base to include a reliance on wild grains including the wheat. There is much evidence that domesticated wheat was widely used in the Levant until about 10,400 years ago, but when this began is still open to debate. Part of Springer Nature. Synthetic hexaploid lines have been shown to be useful sources of variation for abiotic and biotic stress tolerance, as well as agronomic and novel grain quality traits.

The A genome ancestor of wheat is Triticum urartu, and the B genome is thought to have originated with a close relative of Aegilops speltoides. Evolving from an ancestral plant called emmer that still exists today, domestication of wheat was at least 12,000 years ago. By planting these seeds next season, farmers could then continue to grow crops with late stems. CIMMYT has done extensive evaluation of its synthetic-derived lines (Dreccer et al., 2007; Lage and Trethowan, 2008; Rosyara et al., 2019).

Google Scholar, Fu YB, Somers DJ (2009) Genome-wide reduction of genetic diversity in wheat breeding. The origins of our modern wheat can be found in the Karacadag mountain region of what is now southeastern Turkey.

Also, todays wheat varieties have a shallower root system with a large portion of fine roots, so the biomass grows above ground rather than underground. doi:10.1111/j.1365-3040.2009.02107.x, Nevo E, Korol AB, Beiles A, Fahima T (2002) Evolution of Wild Emmer and Wheat Improvement: Population Genetics, Genetic Resources, and Genome Organization of Wheats Progenitor, Triticum dicoccoides.

Knowledge about the geographical origins of these crops and the genes responsible for domestication traits largely pre-dates the era of next-generation sequencing, although sequencing will lead to new insights.

It was a key event in the agricultural revolution that occurred about 10,000 years ago in the Fertile Crescent of the Middle East. 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. Through access to collections of wild relatives, wheat scientists have helped overcome that bottleneck.
