Abstract

Spot blotch disease incited by Cochliobolus sativus is an important disease of barley (Hordeum vulgare L.) crops worldwide. In this study, seedling reactions of 28 six-rowed barley landraces obtained from Osman Tosun Gene Bank, Turkey, and two Turkish barley cultivars (Avcı 2002 and Bülbül 89) to 2 Cochliobolus sativus isolates obtained from Kastamonu and Hatay provinces of Turkey were determined. Virulence difference between the isolates was observed. Isolate obtained from Kastamonu province was more virulent. Two, 18, and 8 landraces showed low, intermediate, and high infection responses to Kastamonu isolate, respectively. Cultivar Avcı 2002 showed intermediate infection response and cultivar Bülbül 89 showed high infection response to Kastamonu isolate. Nine, 18, and 1 landraces showed low, intermediate and high infection responses to Hatay isolate, respectively. Cultivar Avcı 2002 showed low infection response and cultivar Bülbül 89 showed intermediate infection response to Hatay isolate. Landraces 12 and 24 showed low infection responses to both isolates. Landraces 6, 8, 13, 16, 17, and 27 showed low and intermediate infection responses to Hatay and Kastamonu isolates, respectively. Landraces 3, 4, 5, 9, 10, 11, 18, 21, 23, 26, and 28 showed intermediate infection responses to both isolates. Barley landraces showing low and/or intermediate infection responses to Cochliobolus sativus could be used in spot blotch resistance breeding studies or can be planted in areas where spot blotch is common.
