The origins of our modern wheat, according to genetics and archaeological studies, are found in the Karacadag mountain region of what is today southeastern Turkeyemmer and einkorn wheats are two of the classic eight founder crops of the origins of agriculture. In: Smartt J, Simmonds NW (eds) Evolution of crop plants. Triticum spp. It differs from wild wheat in that it has non-shattering spikes, an adaptation that allows the plant to better retain its seeds and to be harvested more easily. Part of wheats adaptability is due to the fact that it occurs both as winter habit varieties (requiring a cold period of 6 to 8 weeks to trigger reproduction), and spring habit varieties (not requiring the cold period).

The culture generally associated with the introduction of wheat and other crops from Asia to Europe is generally the Lindearbandkeramik (LBK) culture, which may have been made up of part immigrant farmers and part local hunter-gatherers adapting new technologies. Compared to emmer wheat, modern wheat has shorter leaf longevity, and a higher net rate of photosynthesis, leaf production rate, and nitrogen content.

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 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. It grows in sporadic and semi-isolated patches and does best in regions with long, hot dry summers and short mild, wet winters with fluctuating rainfall.

Dr. Patrick Byrne highlights examples of contrasting traits in modern wheat and its wild ancestors or heirloom varieties, providing insight into the history of wheat breeding.

This work was supported in part by the China National Science Foundation Grant Nos. Since then, improvement in various traits including resistance to diseases, insect pests, saline and drought stresses, grain yield, and quality were improved through selections by early farmers and then planned hybridization after the discovery of Mendel's laws. From a wild Asian grass to a refined crop that is the staple diet of half the world's population, the domestication of Oryza sativa spans centuries, but the grain's ancestry is hotly contested. Its domestication coincides with the beginning of agriculture and since then, it has been constantly under selection by humans. 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. The spread of wheat outside of its origin is part of the process known as Neolithicization. It was formed from hybridization of domesticated tetraploid wheat [T. turgidum L. ssp. The domestication of wheat around 10,000 years ago marked a dramatic turn in the development and evolution of human civilization, as it enabled the transition from a hunter-gatherer and nomadic pastoral society to a more sedentary agrarian one.
