Virus disease surveys on barley cultivation areas in Jeonnam․Jeonbuk․Gyungnam․Gyungbuk-do were conducted during 2014-2015. In this study, we detected Barley yellow mosaic virus (BaYMV), Barley mild mosaic virus (BaMMV) and Soil-borne wheat mosaic virus (SBWMV) by RT-PCR from barley leaves. These viruses are of great economic importance for wheat and barley, causing significant quantitative and qualitative losses in yield. The result of investigation showed that the field incidence of BaYMV in Buan, Gimje was more than 90% in 2014. The infection field rate of barley virus including Boseong, Gangjin, Haenam, Jangheung in Jeonnam was » 30%. In 2014, double infections by BaYMV and BaMMV was detected in Boseong, Gangjin, Haenam and Jangheung. Only as a low rate BaYMV occurred in various fields of Jeonbuk in 2015. At the same time high infection field ratio of 70% was observed in Gunsan. Also in Yeonggwang was double infection of BaYMV and BaMMV. BaYMV occurred single infection has been confirmed in all of the study area of Gyungbuk and Gyungnam except for Goseong during the investigation period.
