The key domestication-related loci, originated over a wide geographical range, were gradually pyramided through a protracted process. 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. However, advances in sequencing technologies have improved the state of genomic resources for both wheat and barley.

The founder crops (or primary domesticates) are the eight plant species that were domesticated by early Neolithic farming communities in Southwest Asia and went on to form the basis of agricultural economies across much of Eurasia, including Southwest Asia, South Asia, Europe, and North Africa.They consist of three cereals (emmer wheat, einkorn wheat, and barley), four pulses (lentil, pea .

Wheat and barley are two of the founder crops of the agricultural revolution that took place 10,000 years ago in the Fertile Crescent and both crops remain among the world's most important crops. The featured traits are plant height, harvest index, lodging, and shattering. Another early form of wheat called einkorn (T. monococcum) was domesticated at about the same time but has limited distribution today. Sci Rep. 2022 May 20;12(1):8532. doi: 10.1038/s41598-022-11952-9. Springer, Berlin, pp 407456. Germplasm released by the Centerincludes breeding lines for disease and insect resistance, bread making quality, and other traits. 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). Evolving from an ancestral plant called emmer that still exists today, domestication of wheat was at least 12,000 years ago. Mobile DNA 1:6, Bennett MD, Leitch IJ (2010) Plant DNA C-values database (release 5.0, Dec. 2010). The main differences between the wild forms and domesticated wheat are that domesticated forms have larger seeds with hulls and a non-shattering rachis. The effect of domestication on awns in wheat does not match the clear differences between wild and domestic gene pools for other traits. 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. Wild wheat shatters and falls to the ground to reseed itself when ripe, but domesticated wheat stays on the stem for easier harvesting. tauschii with bread wheat. 2014. GENESPACE tracks regions of interest and gene copy number variation across multiple genomes. 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.

Introgression of novel traits from a wild wheat relative improves drought adaptation in wheat. tauschii (DD), giving rise to hexaploid common or bread wheat (T. aestivum), with the AABBDD genome designation. Because the initial product of fertilization between the tetraploid and diploid species is inviable after a few weeks, an embryo rescue procedure must be used in many cases. 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.

Synthetic hexaploids are not directly useful for wheat production because they are typically not adapted to the target growing area and they express wild species traits, such as poor threshing (i.e., the seeds do not separate easily from the enclosing glume tissue) and excessive lodging (Figure 3).
