Barley Yellow Mosaic Virus(BaYMV) is responsible for ane of the most improtant disease in malting Barley in Korea. It is transcitted by soil borne fungus, Polymyza graminis To estimate the occurrence pattern of BaYMV by the physio-chemical property of soil collected from farmer's sield, this study was conducted. The rate of didsease occurrence to BaYMV investigated at 19 spots of 10th regions. The sample soil was collected by 20 pots among an ifected field and analyzed th soil characters in 2002. The rate of disease occurrence to BaYMV was about 79%,60%,65% in Sacheon, Kosung and Hadong areas, respectively, which is malting Barley growing regions but Pohang, Yeongduk, Euesung, Gunwee, which are growing Covered Barley doesn't infected BaYMV. The tested of RT-PCR was showed that the BaYMV, BMMV.SBWMV. were identified in Milyang but the others regions was infected only to BaYMV. The physio-chemical property of soil collected from infected soil show various range such as pH(4.98~8.05), EC(0.44~2.7%),OM(1.61~6.85), P2O5958~519), K(0.22~1.82), Ca(2.3~9.7), Mg(0.5~2.6), Na(0.14~0.43) The correlation coefficient between physio-chemical property fo the infected soil and infection rate shows significant to pH at 5% level. Although OM and Ca were high scores, it doesn't significant at 5% but it need to be more study in future.
