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. Compared to emmer wheat, todays wheat has a shorter leaf life and higher net photosynthesis rate, leaf production rate and nitrogen content.

The main difference between wild forms and domesticated wheat is; domesticated wheat has larger grains with rind and semi-brittle stems. Today, nearly half the world's rice farming takes place in China and India and less than 1% in the United States. Synthetic hexaploids: Harnessing species of the primary gene pool for wheat improvement. 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. tauschii), domestication syndrome factors and other relevant genes could be isolated, and effects of wheat domestication could be determined. Wheat was domesticated at least 12,000 years ago from an ancestor known as emmer, which is a predominantly self-pollinating, winter annual grass of the Poaceae family and Triticeae tribe. Plants, Genes & Agriculture: Sustainability through Biotechnology. 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. By planting these seeds next season, farmers could then continue to grow crops with late stems. 59:461-469. Theor Appl Genet 109:13031310, Stein N (2009) Physical mapping in the Triticeae.

Chapman EA, Thomsen HC, Tulloch S, Correia PMP, Luo G, Najafi J, DeHaan LR, Crews TE, Olsson L, Lundquist PO, Westerbergh A, Pedas PR, Knudsen S, Palmgren M. Front Plant Sci. This results in breeding lines (sometimes called synthetic-derived lines) that have mostly adapted genomes with segments of synthetic hexaploid chromosomes interspersed. The domestication phase thus spread over several centuries and simultaneously concerned several species: einkorn ( Triticum monococcum ), emmer wheat ( T. dicoccum ), barley ( Hordeum vulgare) and rye ( Secale cereale) [13], [15]. HHS Vulnerability Disclosure, Help T. aestivum originated from a cross between domesticated emmer wheat T. dicoccum and the goat grass Aegilops tauschii, most probably in the south and west of the Caspian Sea about 9,000years ago.

BMC Genomics 11:382, Frary A, Doanlar S (2003) Comparative genetics of crop plant domestication and evolution. 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. 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. The earliest cultivated emmer has been found in the southern Levant (Netiv Hagdud, Tell Aswad, other Pre-Pottery Neolithic A sites); while einkorn is found in the northern Levant (Abu Hureyra, Mureybet, Jerf el Ahmar, Gbekli Tepe).

Wheat was one of the first crops to be domesticated more than 10,000 years ago in the Middle East. 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 ).

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. Dr. Patrick Byrne shows harvested heads of the A, B, and D ancestors of wheat, and explains the strategy of creating synthetic hexaploid wheat to increase diversity of cultivated wheat. This major distinguishing feature between wild and domesticated emmer wheat is controlled by two major genes, brittle rachis 2 (Br-A1) and brittle rachis 3 (Br-B1) on the short arms of chromosomes 3A and 3B, respectively. Genetic design and statistical power of nested association mapping in maize. Spelled (T. spelta) and Timopheev wheat (T. timopheevii) evolved from emmer wheats up until the Late Neolithic period, but have few buyers today.
