Screening of Some Registered Turkish Barley Cultivars Reactions Against Rhynchosporium commune

Abstract

Barley is one of the significant cereal used as hay and malt both in the world and in Turkey. There are several abiotic and biotic factors affecting the production and quality of barley. Of these factors, fungal diseases play a vital role. Especially, barley scald (Rhynchosporium commune), a fungal pathogen, is threating the barley grown areas in terms of the quality and the production. One of the most common methods in controlling of this fungal diseasis to develop resistant barley varieties. The study carried out in the laboratories and greenhouses of Field Crop Central Research Institute, Yenimahalle, Ankara in 2020-2021. Aim of this study was to investigate the reaction of 55 registered barley cultivars against barley scald. The results show that Erginel-90 is immun, as well Avcı-2002, Ocak, Kendal, Hevsel, Yükse, Şahin-91 and Akhisar-98 varieties are resistant. On the other hand, Yesevi-93, Tarm-92, Orza-96, Larende, Bülbül-89, Karatay-94 and Ayrancı are detected as susceptible to this disease.
