domestication of wheat
The main differences between the wild forms and domesticated wheat are that domesticated forms have larger seeds with hulls and a non-shattering rachis. To replenish the stock, the FCI and state agencies, as per preliminary .

The effect of domestication on awns in wheat does not match the clear differences between wild and domestic gene pools for other traits.

About 10,000 years ago, T. aestivumderived from a cross between domesticated emmer (Triticum dicoccum) and the goat grass Aegilops tauschii. Cultivated wheat includes the hexaploid bread wheat (Triticum aestivum) and the tetraploid durum wheat (Triticum durum). Human history was transformed with the advent of agriculture in the Fertile Crescent with wheat as one of the founding crops. 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.

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. tauschii accessions directly to the Kansas adapted wheat line KS05HW14, followed by two backcrosses and several generations of self-pollination.

The achievements of domestication genetics and robust research programs in Triticeae genomics are of greatly help in conservation and exploitation of wheat germplasm and genetic improvement of wheat cultivars. From a wild Asian grass to a refined crop that is the staple diet of half the world's population, the domestication of Oryza sativa spans centuries, but the grain's ancestry is hotly contested.
