초록

본 실험은 강원도 마늘 주산지인 삼척시와 정선군의 바이러스 감염 정도를 조사하기 위해 수행되었다. 지역별 100개 시료의 검정을 위해 4종 primer(GLV, LYSV, GCLV, OYDV)를 이용한 RT-PCR 검정을 하였다. 진단 결과 삼척시와 정선군 두 지역에서 바이러스 감염율이 GLV 95%, LYSV 95%, GCLV 92%, OYDV 33%로 조사되었다. 본 조사에 사용된 마늘 검정 시료는 적어도 한 개 이상의 바이러스에 감염되어 있는 것으로 확인되었다. GLV, LYSV, GCLV 3종류의 바이러스 복합감염과 GLV, LYSV, GCLV, OYDV 4종류 바이러스의 복합감염이 각 60%와 25%로 나타났다. GLV, LYSV, GCLV는 두 지역 모두에서 고르게 나타나는 반면 OYDV는 삼척시 보다는 정선군에서 많이 감염되어 있는 것으로 조사되었다. 현재 전국 및 강원도 마늘 포장에서 바이러스 감염은 매우 심각하다. 따라서 마늘의 바이러스 무병종구 및 종구갱신 기술개발이 필요하다.

This research was conducted to investigate the incidence of viral infection in Samcheok-shi and Jeongseon-gun, main garlic growing areas of Gangwon province in Korea. Four primers sets (GLV, LYSV, GCLV, OYDV) were used for RT-PCR to test of 100 samples collected from each location. Infection rates of GLV, LYSV, GCLV and OYDV of garlic samples from Samcheok-shi and Jeongseon-gun were 95, 95, 92 and 33%, respectively. All garlic samples tested in this research were infected at least one virus. Coinfection of 3 kinds of virus (GLV, LYSV and GCLV) and 4 kinds of virus (GLV, LYSV, GCLV and OYDV) were 60 and 25%, respectively. While infections of GLV, LYSV and GCLV were evenly found in both two regions, OYDV infection of garlic samples collected from Jeongseon-gun was higher than Samcheok-shi. Viral infections at garlic fields of whole country and Gangwon province are very serious now. Therefore, it is very necessary to develop technic for virus-free bulb and renew seed bulb of garlic.
