Abstract
Necrotic genotypes of the aboriginal common wheat cultivars (Triticum aestivum L.) from Iran, Afghanistan, Palestine, and Transjordan were studied. It was shown that the cultivars carrying Ne1w and Ne1m alleles prevailed in all geographical regions, while the Ne1s allele was found only in the Afghanistan cultivars. The occurrence of the Ne1s allele may indicate that hexaploid common wheat emerged as a result of spontaneous hybridization between T. durum and Ae. squarrosa. The noncarriers (genotype ne1ne1ne2ne2) occupy virtually all the regions examined. They comprise 77.8% in Iran, 80.8% in Afghanistan, 92.9% in Palestine, and 80.0% in Transjordan. The carriers of the ne1ne1ne2ne2 genotype predominate among the spring cultivars of common wheat.
