Abstract: The study was conducted in the period 2006-2008 at the Institute of Agriculture – Karnobat with the aim to evaluate accessions of winter two-row barley, resistant to loose smut (Ustilago nuda). The samples originate in Syria, Turkey and Bulgaria. They are tested in terms of the Southeast Bulgaria with the aim of finding genotypes with good productive opportunities for their inclusion in the selection program in barley. The results obtained show that the accessions S-7, TF-5, S-6, S-3 and S-9 are the high-yield and could be used as a starting material, combining a high resistance to loose smut and high productivity.
