Wheat is primarily a cool season crop, but is broadly adapted to many types of growing conditions, both irrigated and rainfed, and is especially important as a staple crop in semi-arid conditions. Evolving from an ancestral plant called emmer that still exists today, domestication of wheat was at least 12,000 years ago.

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%. sharing sensitive information, make sure youre on a federal Euphytica 115:121126, Ross-Ibarra J, Morrell PL, Gaut BS (2007) Plant domestication, a unique opportunity to identify the genetic basis of adaptation. Wheat domestication involves a limited number of chromosome regions, or domestication syndrome factors, though many relevant quantitative trait loci have been detected. Bread and durum wheat are both domesticated forms of wild emmer wheat. A creative strategy for addressing the impoverished D genome diversity of common wheat is the development of synthetic hexaploid wheats (McFadden and Sears, 1946; Trethowan and Mujeeb-Kazi, 2008; Ogbonnaya et al., 2013).
