Unique sources of resistance to Fusaruim head blight for durum wheat

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 %.
