Barley kernel discoloration (KD) leads to substantial loss in value through downgrading and discounting of malting barley. The objective of this research is to investigate fungal distribution and varieties resistance to KD in Korean two-rowed barley. Several fungal organisms including Alternaria spp., Fusarium spp., Aspergillus spp., Epicoccum spp. and Rhizopus spp. were isolated from Korean two-rowed barley representing KD. The symptoms of KD were brown and black discolorations of the lemma and palea. The most frequently detected fungal species was Alternaria spp. which exhibited 69.1% and 72.2% in 2011 and 2012, respectively. Epicoccum spp., Fusarium spp., and Aspergillus spp. were also detected. Fusarium spp., primary pathogen of barley head blight, were rarely occurred in the 2011 and their occurrence increased to 4.7% in 2012. Twenty cultivars of Korean two-rowed barely were evaluated to KD. The average percentage of KD was 8.0?36.0% in 2011 and 5.2?36.6% in 2012. Two cultivars (‘Sacheon 6’ and ‘Dajinbori’) showed KD of 6.2% to 8.8% and determined resistant, however ‘Samdobori’ and ‘Daeyeongbori’ demonstrating KD of 22.2?36.6% were highly susceptible. ‘Jinyangbori’, ‘Danwonbori’, ‘Sinhobori’ and ‘Kwangmaegbori’ showing KD of less than 15% were moderately resistant cultivar. |
