Dreccer MF, Borgognone MG, Ogbonnaya FC, Trethowan RM, Winter B. Ancient Hybridizations among the Ancestral Genomes of Bread Wheat. Most of the 25,000 different forms of modern wheat are varieties of two broad groups, called common wheat and durum wheat. This results in breeding lines (sometimes called synthetic-derived lines) that have mostly adapted genomes with segments of synthetic hexaploid chromosomes interspersed.

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]. Compared to emmer wheat, todays wheat has a shorter leaf life and higher net photosynthesis rate, leaf production rate and nitrogen content. This was elegantly demonstrated by John Bennet Lawes in the 1880s when he decided to allow part of the famous long-term Broadbalk experiment at Rothamsted to return to its natural state ().He therefore left part of the wheat crop unharvested in 1882 and .

It differs from wild wheat in that it has non-shattering spikes, an adaptation that allows the plant to better retain its seeds and to be harvested more easily. Provided by the Springer Nature SharedIt content-sharing initiative, Over 10 million scientific documents at your fingertips, Not logged in Molecular markers were initially used to calculate distance (relatedness), genetic diversity and to generate genetic maps which were useful in cloning major domestication genes. According to French botanist Agathe Roucou and colleagues, the domestication process also caused multiple changes in the plant that were generated indirectly. These lines can be grown and evaluated like normal wheat in hopes of finding improvements in qualitative or quantitative traits due to the inserted synthetic hexaploid segments. Dr. Patrick Byrne highlights examples of contrasting traits in modern wheat and its wild ancestors or heirloom varieties, providing insight into the history of wheat breeding.
