Fifteen accessions of Triticum dicoccum tetraploid wild relatives of durum wheat were screened for Type II Fusarium head blight (FHB) resistance. Single florets on spike at 50 % anthesis were inoculated with spores of Fusarium graminearum and symptoms were scored at 21 days after inoculation. The range of infected florests varied from 6 % to 100 % compared to Langdon atypical sensitive durum wheat cultivar at 75 %. Six selected the most resistant accessions were used in the trial, which range of infection varied from 6 % to 8 %.
