Spelled (T. spelta) and Timopheev wheat (T. timopheevii) evolved from emmer wheats up until the Late Neolithic period, but have few buyers today. The domestication of wheat (Triticum aestivum L.) from wild grasses in the Middle East is a fascinating story that resulted in one of the worlds most important and widespread crops.

Figure 1. It was domesticated at least 12,000 years ago, created from a still-living ancestor plant known as emmer. The main differences between the wild forms and domesticated wheat are that domesticated forms have larger seeds with hulls and a non-shattering rachis. While some scientists argue that this is a fairly rapid process of several centuries; Others argue that the process from the cultivation of wheat to its domestication is almost 5,000 years old.

Its domestication coincides with the beginning of agriculture and since then, it has been constantly under selection by humans. volume28,pages 281301 (2011)Cite this article.

Your access to this service has been limited. 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. China is a major producer of grains such as wheat, corn, and rice. Wheat domestication involves a limited number of chromosome regions, or domestication syndrome factors, though many relevant quantitative trait loci have been detected. 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]. Of these traits, grain retention and threshability, yield improvement, changes to photoperiod sensitivity and nutritional value are most pronounced between wild and domesticated forms. Kishii (2019) has compiled genes that have been identified or transferred from Ae. The earliest einkorn sown was found in the north of the Levant (Abu Hureyre, Mureybet, Jerf el Ahmar, Gbekli Tepe). 2023 Springer Nature Switzerland AG. Wheat seeds, crumbs, and pollen were not found at Bouldnor Cliff, but DNA sequences from the sediment match Near Eastern wheat, which is genetically different from the LBK forms. Synthetic hexaploids: Harnessing species of the primary gene pool for wheat improvement. The sediments were laid down about 8,000 years ago, several centuries earlier than the European LBK sites. KSCX2-YW-Z-0722, the CAS Strategic Priority Research Program Grant No. Compared to emmer wheat, modern wheat has shorter leaf longevity, and a higher net rate of photosynthesis, leaf production rate, and nitrogen content. Other scholars have questioned the date, and the aDNA identification, saying it was in too good a condition to be that old. 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. Curr Opin Plant Biol.
