Gepts P. 2018. Wheat: Vital grain of civilization and food security. The availability of reference genomes for wheat and some of its progenitors, as well as for barley, sets the stage for answering unresolved questions in domestication genomics of wheat and barley. It was domesticated at least 12,000 years ago, created from a still-living ancestor plant known as emmer. When wild wheat is ripe, the rachisthe stem that keeps the wheat shafts togethershatters so that the seeds can disperse themselves. Assume that it is also an exporting country in the market for grain. By planting these seeds next season, farmers could then continue to grow crops with late stems. doi:10.1155/2008/896451, Gustafson P, Raskina O, Ma X, Nevo E (2009) Wheat evolution, domestication, and improvement.

Theor Appl Genet 71:518526, Sood S, Kuraparthy V, Bai G, Gill BS (2009) The major threshability genes soft glume (sog) and tenacious glume (Tg), of diploid and polyploid wheat, trace their origin to independent mutations at non-orthologous loci. The site is secure. When wild wheat ripens, the stems, the part that holds the wheat stems together, break down so that the seeds can self-pollinate and sprout faster without the husk. Domestication has genetically not only transformed the brittle rachis, tenacious glume and non-free threshability, but also modified yield and yield components in wheat. Today, nearly half the world's rice farming takes place in China and India and less than 1% in the United States. This wild species was domesticated to form emmer wheat (Triticum turgidum ssp.

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.

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%.
