Abstract

The incidence of virus disease on peppers was investigated at the 52 areas in the whole country in 2002, 2004 to 2006. Among the six viruses, Cucumber mosaic virus (CMV), Pepper mottle virus (PepMoV), Pepper mild mottle virus (PMMoV), Broad bean wilt virus 2 (BBWV2), Tobacco mild green mosaic virus (TMGMV) and Tomato spotted wilt virus (TSWV), infecting peppers in Korea, the incidence of CMV, PepMoV, PMMoV and BBWV2 was 29.4%, 13.6%, 14.3%, 25.6%, orderly. TMGMV and TSWV had the same low infection rate of 1.0%. The infection rate of CMV was higher as 53.3% and 34.2% in 2002 and 2004, but it was decreased to 18.2% and 11.9% in 2005 and 2006, respectively. The infection rate of BBWV2 was lower as 1.3% in 2002 and 1.8% in 2004, but it was increased abruptly to 41.3% in 2005 and 58.2% in 2006. For the types of mixed infections of pepper viruses, the incidence of CMV+PepMoV was 62.6% in 2002 and 50.0% in 2004, and that of CMV+BBWV2 was increased suddenly from 33.3% in 2005 to 83.2% in 2006. The triplex infection of CMV+BBWV2+PepMoV was 6.4% in average. CMV caused severe mosaic and BBWV2 induced ring spots, and the two mixed virions caused chlorosis on the leaves of red peppers. TSWV induced the typical symptoms of multiple ring spots on the leaves and fruits of red peppers.

전국 52개 지역에서 2002년, 2004년에서 2006년, 4년 간 고추 바이러스 이병물을 채집하여 바이러스 감염양상을 조사하였다. 감염된 바이러스 종류는 Cucumber mosaic virus(CMV), Pepper mottle virus(PepMoV), Pepper mild mottle virus(PMMoV), Broad bean wilt virus 2(BBWV2), Tobacco mild green mosaic virus(TMGMV), Tomato spotted wilt virus(TSWV) 6종이었다. CMV, PepMoV PMMoV와 BBWV2의 발생률은 각각 29.4%, 13.6%, 14.3%, 25.6%이었다. TMGMV와 TSWV의 발생률은 1.0%로 매우 낮았다. 2002년과 2004년의 CMV 발생률은 53.3%와 34.2%로 가장 높았으나 2005년과 2006년에는 18.2%와 11.9%로 감소하였다. BBWV2의 발생률은 2002년에 1.3%, 2004년에 1.8%로 낮았으나, 2005년에 41.3%, 2006년에 58.2%로 크게 증가하였다. CMV+BBWV2의 발생률은 2002년에 0.0%, 2004년에 2.1%이었으나 2005년과 2006년에 각각 33.3%와 83.2% 증가하여 BBWV2의 단독감염과 함께 복합감염에서도 급격히 증가하였고 CMV+BBWV2+PepMoV의 삼중 복합감염률은 평균 6.4%이었다. CMV는 고추 잎에 심한 모자이크병징, BBWV2는 원형반점 병징을 일으키며, CMV와 BBWV2의 복합감염 경우에는 퇴록병징을 일으켰다. TSWV는 고추 잎과 과일에 전형적인 다중 원형반점을 일으켰다.
