Oxford University Press, Oxford. Ogbonnaya et al., 2013 state that in the 7 years previous to their review, 17% of wheat lines in all of CIMMYTs international trials were synthetic-derived, but that number increased to 35% for the Semiarid Wheat Yield Trial. Wheat is one of the most important grain crops in the world, and consists mainly of two types: the hexaploid bread wheat (Triticum aestivum) accounting for about 95% of world wheat production, and the tetraploid durum wheat (T. durum) accounting for the other 5%.

Drought adaptive traits and wide adaptation in elite lines derived from resynthesized hexaploid wheat. Evolution and Adaptation of Wild Emmer Wheat Populations to Biotic and Abiotic Stresses. Wild wheat shatters and falls to the ground to reseed itself when ripe, but domesticated wheat stays on the stem for easier harvesting. Video 3. 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].

We examined 9844 ancient charred spikelets from four archaeological sites located in northern Syria and southeastern Turkey dating between 10,200 and 6500 yr B.P. While there is evidence that the inclusion of wheat and wild grains has expanded peoples diets, some scientists say there is no evidence that these plants were deliberately planted.

But additional experiments run by British evolutionary geneticist Robin Allaby and preliminarily reported in Watson (2018) have shown that ancient DNA from undersea sediments is more pristine than that from other contexts. Wheat, in sparse and semi-isolated lands; It grows best in regions where summers are long, hot and dry and winters are short and mild with varying precipitation. According to botanist Agathe Roucou and colleagues, the domestication process indirectly caused multiple changes in the plant. 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.
