Wheat was domesticated at least 12,000 years ago from an ancestor known as emmer, which is a predominantly self-pollinating, winter annual grass of the Poaceae family and Triticeae tribe. The International Maize and Wheat Improvement Center (CIMMYT) has been a leader in producing and utilizing synthetic hexaploids, with over 1,500 synthetics developed (Mujeeb-Kazi and Hettel, 1995; Rosyara et al., 2019). While some scientists argue that this is a fairly rapid process of several centuries; Others argue that the process from the cultivation of wheat to its domestication is almost 5,000 years old.
