Summary: | Tomato yellow leaf curl virus (TYLCV) disease survey of tomato plants cultivated at Youngam, Changseong and Hwasun in Jeonnam Province was conducted in 2012 to 2013. To detect TYLCV in the field, PCR assay was performed using genomic DNAs extracted from tomato samples. According to cropping pattern, 23 and 59.4% of TYLCV infections were shown in semi-forcing and retarding cropping systems, respectively, and the frequencies of diseased plants were 0.4 and and 13.1% in the two cropping systems, respectively. Especially, TYLCV incidences in the susceptible varieties were 24.3 and 83.0% in semi-forcing and retarding cropping systems, respectively. Resistant varieties showed 9.1% infection in retarding cropping system but did not in semi-forcing cropping system. Also, TYLCV was occurred on early June after transplanting on April and at approximate 20 days after transplanting on August or September. 전남지역의 영암, 장성, 화순 등 주요 재배주산지에서 2012년부터 2013년까지 2년동안 토마토황화잎말림바이러스 병의 발생현황을 조사하였다. 바이러스는 토마토 시료로부터 전체 DNA를 추출하여 PCR을 실시하였다. 토마토 재배작형별 바이러스 발병포장율은 반촉성작형은 23%, 억제작형은 59.4%였으며, 이병주율은 각각 0.4%, 13.1%였다. 저항성품종 재배시에는 작형에 관계없이 발병율이 매우 낮았으며, 감수성 품종 재배시에는 발병포장율은 반촉성은 24.3%로 낮았으나, 억제작형은 83.0%로 매우 높았다. 하지만 저항성 품종 재배시에는 발병 포장율은 반촉성은 발생되지 않았고, 억제작형은 9.1%였다. 토마토황화잎말림바이러스는 4월 정식시 6월 상순부터 발생하였고, 8월과 9월에 정식하였을 때 20일 후부터 발생하기 시작하였다. |
