Abstract

Red wild einkorn, Triticum urartu, is increasingly being recognized as a source of genetic material for the improvement of wheat grain quality and for conferring resistance to various diseases such as Powdery Mildew and Leaf Rust resistance including the virulent race Ug99. Two hundred and two samples of T. urartu collected throughout much of its distribution were investigated by amplified restriction length polymorphism, AFLP™ to estimate the genetic diversity within and among them. To infer the genetic structure of the populations the data were subjected to analyses of molecular variance, AMOVA. The analyses of the samples enabled us to assess the location(s) of the richest area(s) in genetic diversity of the species. This area is found in north-western Syria and the adjacent South Turkey. It was also found that the similarity among populations did not reflect on their geographic closeness.
