Abstract

This is the first report on. rice black-streaked dwarf virus in Korea. The occurrence of this virus in Korea was confirmed by symptoms On rice Plants, Vector transmission and microscopic Observation in 1975. The smaller brown planthopper, Laodelphax striatellus FALLEN, transmits this virus which is spherical with a diameter of about 60 nm. Higher infection was observed in earlier transplanted rice with higher levels of fertilizer than in normal and standard cultivation fields.

지금까지 우리나라에 발생되지 않았던 새로운 수도 바이러스병인 벼 흑조위축병에 대하여 실시한 확인 및 동정 실험결과는 다음과 같았다. 1) 애멸구(Laodelphax Striatellus FALLEN)가 벼 흑조위축병을 매개하였다. 2) 바이러스의 입자는 구형이었으며 직경은 약60nm이었다. 3) 이 병은 령, 호남지방 및 충청북도에서 발생하였다. 4) 이앙시기가 빠를수록, 바맥일수록 이병주율이 높았다.
