Summary:July in 2005, we collected infected maize plant that showing stripe dwarf disease on maize leaf in Jeonbuk provinces including Gochang-gun and conducted genomic dsRNA extraction and RT-PCR. Genomic dsRNA was extracted directly in infected maize plant and electrophoresis in agarose gel. We confirmed 10 segments of genomic dsRNA. We conducted RT-PCR by genomic dsRNA and specific primer of S7, S8 and S10. As a result, specific band of expected size was confirmed respectively. In the results of dsRNA and RT-PCR analysis, we confirmed Rice black-streaked dwarf fijivirus (RBSDV) from naturally infected maize plant. Occurrence of RBSDV of maize plant was dealt 22 ha's damage in maize field. The occurrence rate was 80% in a lot of places of disease. 2005년 7월 전북고창 지역에서 옥수수에 줄무늬 위축증상을 나타내는 이병주를 채집하여 게놈 dsRNA 분리 및 RT-PCR 반응을 실시하였다. 게놈 dsRNA 분리는 이병엽 100mg에서 직접 dsRNA를 추출하여 agarose gel에서 전기영동 하였으며, 10개의 분절을 확인하였다. 추출한 dsRNA를 주형으로 하여 S7, S8, S10 full-length 특이적인 primer를 제작하여 RT-PCR을 실시하였다. 그 결과 각각의 분절에서 예상되는 크기의 밴드를 확인하였다. 고창지역의 사료용 옥수수 재배지에서 RBSDV의 발생면적은 약 22ha에 달하였으며 발생이 심한 곳은 약 80%의 이병율을 나타내기도 하였다.
