Wheat geneticists and breeders have a long history of identifying useful genes in wild wheat relatives and incorporating them into improved varieties. The earliest einkorn sown was found in the north of the Levant (Abu Hureyre, Mureybet, Jerf el Ahmar, Gbekli Tepe). 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.

PMC 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. Another table in Kishii (2019) compiles genes from Aegilops species other than Ae. Compared to emmer wheat, modern wheat has shorter leaf longevity, and a higher net rate of photosynthesis, leaf production rate, and nitrogen content. Genes from Aegilops species and other wild relatives have been extremely important for improving a number of traits in wheat, especially disease resistance. 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.

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 ). Throughout the domestication process of wheat, the plant phenotype has undergone both rapid (within a few hundred years) and slow (thousands of years) changes, such as the weakening of the. 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. Cultivation of this species usually involves flooded conditions in paddies, although it is also grown in upland regions.
