Determination of the Reactions of Some Barley Cultivars and Genotypes to Scald Under Greenhouse and Field Conditions

Abstract

The reactions of 36 barley cultivars and 683 barley genotypes to scald were investigated under greenhouse seedling and field adult plant conditions. Among the 683 barley genotypes tested 44% and 39 % were found to be resistant to moderately resistant in the seedling and adult plant stage, respectively. In the genotype resistance study, a significant P=0. 0001 correlation was found between the seedling resistance and adult plant resistance r=0.53 . The cultivars Çetin 2000, Avcı 2002, Erginel 90, Kıral 97, Kaya 7794, Akhisar 98, Zafer 160 and Yeşilköy 387 were found as resistant under both greenhouse and field conditions. The cultivars Çıldır 02, Vamıkhoca and Quantum were found as susceptible under greenhouse conditions; however, they were found as resistant under field conditions. Twenty-five cultivars were susceptible under both greenhouse and field conditions
