Einkorn's Debut	Volume 51 Number 1, January/February 1998
by Mark Rose

The wild progenitor of einkorn wheat, one of the first crops to be domesticated (ca. 9000 B.C.), has been identified genetically in southeastern Turkey, according to a report in the journal Science. Manfred Heun of the Agricultural University of Norway, along with Norwegian, German, and Italian colleagues, examined the DNA of 68 lines of cultivated einkorn (Triticum monococcum monococcum), 194 lines of wild einkorn (T. m. boeoticum) from nine geographical regions within the Fertile Crescent, and nine lines of a weedy einkorn (T. m. aegilopoides) found in the Balkans.

Cultivated einkorns proved closely related to one another and to weedy einkorn. Significantly, both cultivated and weedy varieties are closely related to wild einkorn found in one region, the Karacadag Mountains of southeastern Turkey. The wild einkorn from that area proved to be distinct from other wild types and may be the forebear of the domestic variety.

Eleven of 19 lines of wild einkorn from the Karacadag Mountains are particularly close to cultivated einkorn but have clear wild characteristics, including a brittle stalk yielding a few small grains. In cultivated einkorn the stalk is tougher (which makes the grain easier to harvest), and the seeds are larger and more numerous. The weedy einkorn, closely related to both wild and cultivated types, appears to be an intermediate form with some characteristics of cultivation (the stem is somewhat tougher than in wild plants, the seeds are intermediate in weight, and there are comparable numbers of seeds as in cultivated plants).

Wild or cultivated einkorn grains have been found at several early Neolithic sites in Turkey near the Karacadag Mountains, including Cafer Höyük, Cayönü, and Nevali Cori. Wild and cultivated seeds have also been found at Abu Hureya to the south in Syria.
