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. http://www.kew.org/cvalues/, Brner A, Korzun V, Worland AJ (1998) Comparative genetic mapping of loci affecting plant height and development in cereals. Another early form of wheat called einkorn (T. monococcum) was domesticated at about the same time but has limited distribution today. Theor Appl Genet 112:373381, Nalam V, Vales MI, Watson CJW, Johnson EB, Riera-Lizarazu O (2007) Map based analysis of genetic loci on chromosome 2D that affect glume tenacity and threshability, components of the free-threshing habit in common wheat (Triticum aestivum L.). This hybridization is believed to have occurred only 8000 to 10,000 years ago, most likely in an area south of the Caspian Sea in present-day Iran (Gepts, 2018). The earliest present evidence for the utilization of wheat comes from the Ohalo II site in Israel, where the wild, brittle tetraploid wheat Triticum dicoccoides, dated as 19,000 years old, was found, suggesting the initial steps towards sedentism and cereal agriculture (Kislev et al. 2007. In: Soltis D, Soltis P (eds) Isozymes in Plant Biology. Kishii (2019) has compiled genes that have been identified or transferred from Ae. Today, it grows along the Near Eastern Fertile Crescent in countries such as Israel, Jordan, Syria, Lebanon, eastern Turkey, western Iran, and northern Iraq. PubMedGoogle Scholar. 1992). Above photo credits (left to right): Phil Westra, Pat Byrne, Mike May. 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. spelta) was widely cultivated in Europe until the 20 th century when it was largely replaced by bread wheat due to the agronomic superiority of the latter; however, spelt is still grown to a limited extent in Central Europe, particularly on marginal land, and may provide a 2008. The Wheat Genetics Resource Center at Kansas State University has been a leader in collecting, conserving, and exploiting wild wheat relatives for crop improvement. It is distributed throughout the Near Eastern Fertile Crescent, including the modern countries of Israel, Jordan, Syria, Lebanon, eastern Turkey, western Iran, and northern Iraq. GENESPACE tracks regions of interest and gene copy number variation across multiple genomes.

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 distribution of wheat outside of its place of origin is part of the process known as "Neolithicization." Neolithic Cultivation of Tetraploid Free Threshing Wheat in Denmark and Northern Germany: Implications for Crop Diversity and Societal Dynamics of the Funnel Beaker Culture. A creative strategy for addressing the impoverished D genome diversity of common wheat is the development of synthetic hexaploid wheats (McFadden and Sears, 1946; Trethowan and Mujeeb-Kazi, 2008; Ogbonnaya et al., 2013). Crop Sci 36:228233, Faris J, Gill BS (2002) Genomic targeting and high resolution mapping of the domestication gene Q in wheat. The purpose of this chapter is to explain how wheat originated in the Fertile Crescent of the Middle East, and how knowledge of wheats ancestors informs strategies for continued improvement of the cultivated crop. Their improved yield performance under drought stress conditions appears to be due at least in part to shifts in their rooting profile, whereby a greater proportion of root biomass is produced deeper in the profile (Lopes and Reynolds, 2011; Reynolds et al., 2008). These includes genes for resistance to leaf rust, stem rust, stripe rust, powdery mildew, Septoria tritici, Septoria nodorum, tan spot, cyst nematode, root knot nematode, Hessian fly, greenbug, Russian wheat aphid, wheat curl mite, and soil-borne cereal mosaic virus. tauschii accessions than occurred in nature. (Gramineae- Triticinae). In: Chrispeels MJ, Gepts P (editors). DNA analysis of wheat and its wild relatives led Marcussen et al. Science. Wild emmer genome architecture and diversity elucidate wheat evolution and domestication. Much later, another hybridization occurred between domesticated emmer wheat (AABB) and Ae.

Ecological genomics of natural plant populations: the Israeli perspective. Further tests at Bouldnor Cliff have identified a submerged Mesolithic site, 16 m (52 ft) below sea level. The origins of our modern wheat can be found in the Karacadag mountain region of what is now southeastern Turkey.

About 10,000 years ago, T. aestivumderived from a cross between domesticated emmer (Triticum dicoccum) and the goat grass Aegilops tauschii. Compared to emmer wheat, modern wheat has shorter leaf longevity, and a higher net rate of photosynthesis, leaf production rate, and nitrogen content.
