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%. Science 316:18621866, Dunford RP, Griffiths S, Christodoulou V, Laurie DA (2005) Characterisation of a barley (Hordeum vulgare L.) homologue of the Arabidopsis flowering time regulator GIGANTEA. Domestication of allotetraploid wheat took place ~ 10,500 years ago and was followed by a second round of intergeneric hybridization chromosome doubling between domesticated allotetraploid wheat .

Expert Answer. monococcum), which is still grown in remote parts of Turkey, Italy, and Spain. 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. 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.

The sediments were laid down about 8,000 years ago, several centuries earlier than the European LBK sites. The main difference between wild forms and domesticated wheat is; domesticated wheat has larger grains with rind and semi-brittle stems. The genetic changes during domestication mean that modern wheats are unable to survive wild in competition with better adapted species.

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.
