The exact origin of Khorasan wheat remains unknown. Described by John Percival in 1921, this ancient grain probably originates from the Fertile Crescent and derives its common name from the historical province of Khorasan which included a large portion of northeastern Iran into Afghanistan and Central Asia to the river Oxus. Some Turkish scientists have suggested that it originated in Anatolia. Khorasan region stretches into Pakistan covering the province of KP Khyber Pakhtunkhwa
Khorasan wheat was probably continuously cultivated at small scales and for personal use in Near East and Central Asia and in Northern Africa. However, it has not been commercially produced in modern times. In 1949, when the grain reached the USA, it did not raise a lot of interest and therefore fell into disuse. In 1977, Mack and Bob Quinn, two farmers from Montana, decided to cultivate this ancient grain. In 1990, they registered the protected cultivated turanicum variety QK-77 as the trademark Kamut.
