Mol Biol Evol 19:17971801, PubMed 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. The key domestication-related loci, originated over a wide geographical range, were gradually pyramided through a protracted process. Wheat was one of the first crops to be domesticated more than 10,000 years ago in the Middle East.

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. tauschii accessions is to develop a Nested Association Mapping population (NAM), a method described for maize by Yu et al. Therefore, the synthetic lines are typically crossed to an adapted wheat cultivar, then backcrossed once or twice to the adapted cultivar, followed by selection. Expert Answer. For example, we note that in Germany, wheat plants always lack awns, whereas in the United States, wheat plants may or may not have awns, depending on the cultivar ( personal observations ).

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. But other experiments led by evolutionary geneticist Robin Allaby and originally published in Watson (2018) suggest that ancient DNA from submarine sediments is less degraded than in other environments. Kishii (2019) has compiled genes that have been identified or transferred from Ae. One possible way that might have occurred is that farmers harvested wheat after it was ripe, but before it self-dispersed, thereby collecting only the wheat that was still attached to the plant. This site first gained attention during the 1961-65 excavations due to the recovery of primitive . 59:461-469. Cultivation of this species usually involves flooded conditions in paddies, although it is also grown in upland regions.
