摘要

Triticum urartu is a wild diploid wheat identified as donor of the A genome in the durum and bread wheats. This species has its natural distribution zone in the Fertile Crescent. Nine populations from this zone (five Lebanese and four Turkish) were analysed for the variation in the loci coding of endosperm storage proteins: glutenins (Glu-A u 1 and Glu-A u 3) and gliadins (Gli-A u 1 and Gli-A u 2). Up to 10 alleles for the Glu-A u 1 locus, 16 for the Glu-A u 3 locus, 15 for the Gli-A u 1 locus and 18 for the Gli-A u 2 locus were found. The Turkish populations showed greater diversity than the Lebanese populations, distributing mainly within populations, whereas the inverse process takes place for the Lebanese populations. The values of the genetic diversity indicated that, although these materials showed high level of variability, exist a real risk of genetic erosion.
