Bazı arpa çeşitlerinin Drechslera teres f. teres ’e fide dönemi tepkilerinin belirlenmesi

Seedling stage reactions of 25 barley cultivars were evaluated against three isolates of Drechslera teres f. teres causing net form of net blotch of barley under greenhouse conditions. Isolates were obtained from Eskisehir, Diyarbakir, and Sivas provinces of Turkey. The reactions of cultivars to fungal isolates ranged between resistant-moderately resistant and moderately susceptible-susceptible. Cultivars Bulbul 89 and Ince 04 were found as the most susceptible cultivars, which were followed by cvs. Cildir 02, Ozdemir 05 and Hamidiye 85. Cultivar Harman was found as the most resistant cultivar. This cultivar was followed by cvs Lord, Yercil 147, Erginel 90, Bilgi 91, Unver, and Aydan Hanim. Virulence differences among the isolates were observed. Diyarbakir isolate was the least virulent isolate whereas Sivas isolate was the most virulent isolate.
