Апстракт

Rhynchosporium commune, the causal agent of leaf disease and also known as leaf blotch or scald, affects plant growth and accordingly yield in barley worldwide. The aim of the study was to determine difference in virulence of isolates of R. commune (Rc) from main barley growing areas of Turkey. In the study, a total of 37 isolates were obtained from Central Anatolia (Ankara, Konya, Eskişehir, Kırşehir and Çorum provinces) in 2013 and 2014. To reveal difference in virulence of the isolates, susceptible cultivar Aydanhanımandcvs. Çetin 2000 and Tokak 157/37 were used as host plants. The study, set up a factorial design in randomized plots with three replications, was conducted under controlled conditions in Ankara. Cultivars at the seedling stage were inoculated by spraying inoculum on them. Using 0 to 4 scale, disease ratings were done. In the cluster analysis, the isolates were separated into four different groups. Mean disease severity (MDS) of the isolates on the cultivars was 1.92, while they were 2.59, 2.05 and 1.14 in cv. Tokak, Aydanhanım and Çetin 2000, respectively. Disease severity (DS) varied from 0.01 to 3,5 among the cultivars. With 2.83 and 2.66 DS rates, isolate 37 and 31 were the most virulent, respectively. However, the least virulent isolates were 10(1.17) and 11(1,0), 12(1,0), 13(1,0), 25(1,0). Differences determined among isolates and cultivars and isolate x cultivar interactions were significant statistically (P<0.01, R2 0,94). The study showed that virulences of the isolates of Rc were significantly different on the hosts tested.
