A separate lineage of the A genome led to domesticated einkorn wheat (Triticum monococcum ssp. The genetic changes during domestication mean that modern wheats are unable to survive wild in competition with better adapted species. 2008. Ancient forms have built-in coordination between above and below ground functioning, but the human selection of other traits has forced the plant to reconfigure and build new networks. Field Crops Research 100:218228. According to French botanist Agathe Roucou and colleagues, the domestication process also caused multiple changes in the plant that were generated indirectly.

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. Wheat was one of the first crops to be domesticated more than 10,000 years ago in the Middle East. Bread wheat (Triticum aestivum) accounts for approximately 95 percent of all wheat consumed in the world today; the other five percent consists of durum or hard wheat (T. turgidum ssp) used in pasta and semolina products. Most of the 25,000 different forms of modern wheat are varieties of two broad groups, called common wheat and durum wheat. Genetics 164:311321, PubMed Winter-habit synthetic hexaploid lines from CIMMYT growing in Fort Collins, Colorado. The domestication of wheat around 10,000 years ago marked a dramatic turn in the development and evolution of human civilization, as it enabled the transition from a hunter-gatherer and nomadic pastoral society to a more sedentary agrarian one. In: Dorofeev VF, Korovina ON (eds) Flora of Cultivated Plants, vol 1. Gepts P. 2018.
