Assessment of the Seedling Reactions of Some Turkish Barley Cultivars to Barley Stripe

Seedling reactions of 15 barley cultivars grown in Turkey were determined under greenhouse conditions to five isolates of Drechslera graminea, the causal. agent of barley stripe disease. Isolates were collected from different parts of Ankara province. Differences were observed among the reactions of the cultivars to the isolates of the fungus. There were also pathogenicity differences among the isolates. The cultivars Cumra 2001 and Yercil 147 were resistant to all five isolates. Cultivar Sladoran was resistant to 4 isolates. The cultivars Erginel 90, Orza 96, Cetin 2000 and Aydanhanim were susceptible to three isolates of the fungus. The reactions of other varieties ranged between resistant and susceptible depending on the isolates. Isolate Dg3 was the most virulent.
