Abstract

Leaves of twenties radish (Raphanus sativus L.) inbred lines were mechanically inoculated with Turnip mosaic virus (TuMV) strain HY to evaluate TuMV resistance of the radish inbred lines. The inoculated radish plants were incubated at $22^{\circ}C{\pm}3^{\circ}C$ and resistance assessment was examined using symptom development for 4 weeks. Based on the reactions of differential radish inbred lines, 16 radish lines were produced mild mosaic, mottling, mosaic and severe mosaic symptoms by TuMV infection. These results were confirmed by RT-PCR analysis of TuMV coat protein gene, suggesting that TuMV is responsible for the disease symptoms. Four resistant radish lines did not induce systemic mosaic symptoms on upper leaves and chlorosis in stem tissues for 4 weeks, showing they were symptomless by 8 weeks. Further examination of TuMV infection in the 4 radish lines showed no TuMV infection in all systemic leaves. These results suggest that the 4 radish lines are highly resistant to TuMV.

무(Raphanus sativus L.) 육종 계통들에 대한 순무모자이크 바이러스(Turnip mosaic virus, TuMV) 저항성을 평가하기 위하여, 20개 무 육종계통들의 잎에 순무모자이크바이러스 BR 병원성을 가지는 국내 분리 계통을 즙액 접종하였다. 순무모자이크바이러스를 접종한 무 개체들은 $22^{\circ}C{\pm}3^{\circ}C$에서 재배하였으며 4주 동안 바이러스 병징 발현을 육안으로 조사하여 저항성을 평가하였다. 순무모자이크바이러스 감염에 의해서 무 육종계통들의 다른 병징 발현에 의해 분석한 결과, 16개 무 계통은 약한 모자이크, 모틀링에서 심한 모자이크 전신 병징을 보였으며 감수성으로 판별되었다. 이러한 결과는 순무모자이크바이러스 외피단백질 유전자에 대한 특이적 역전사중합효소연쇄반응에 의하여 확인되어, 순무모자이크바이러스가 병징을 발현시킨 원인이었다. 이와는 다르게 4개 무 육종계통들에서는 모자이크 등 전신 감염 병징이 발현되지 않았으며, 동일한 무 육종 계통들의 개체들에서 8주 동안 병징이 관찰되지 않았다. 역전사중합효소연쇄반응으로 조사한 결과 4개 무 육종 계통들의 상엽들에서 순무모자이크바이러스가 검출되지 않았다. 이런 결과는 4개 무 육종계통들이 순무모자이크바이러스에 대한 강한 저항성을 가지고 있음을 예시해준다.
