초록
벼멸구에 대(對)한 벼품종간(品種間)의 피해(被害)와 수량(收量)을 조사(調査)하였다. 1983 년(年) 전남(全南) 해남(海南)에서 29개(個) 벼품종(品種)을 살충제무산포구(殺蟲劑無散布區), 살충(殺蟲) 및 살충제무산포구(殺蟲劑無散布區), 살균제무산포(殺菌劑無散布) 두어 이앙(移秧)하고 충밀도(蟲密度), 벼고사시기(枯死時期), 수량(收量)을 조사(調査)하였다. 삼강(三剛)벼, 가야(伽倻)벼, 한강(漢江)찰벼, 청청(靑靑)벼는 극히 낮은 밀도(密度)와 피해(被害)가 없었고 밀양(密陽) 30호(號)와 원풍(圓豊)벼는 중간정도(中間程度)의 밀도(密度)와 피해(被害)를 보였고 그 이외(以外) 품종(品種)은 높의 밀도(密度)와 고사현상(枯死現狀)을 나타냈다. 살충제무산포(殺蟲劑無散布)에 의한 수량(收量) 감수효과(減收效果)가 적었던 품종(品種)은 가야(伽倻)(12%), 삼강(三剛)벼(29%), 한강(漢江)찰벼(35%)였고 감수효과(減收效果)가 컷던 품종(品種)은 복광(福光)벼(260%), 팔금(八錦)(223%), 송전(松前)벼(200%), 관악(冠岳)벼(200%)였다.
Plant damages and yields of the different rice cultivars to brown planthopper (BPR), Nilaparvata lugens S., were observed for the evaluation of varietal resistance in paddy fields. Twenty nine Korean cultivas were transplanted in paddy fields with three plots of no insecticide, no insecticide and fungicide, and no fungicide at Haenam, southern coastal area in 1983. Among 6 varieties with BPR resistant genes, Samgang, Gaya, Hangangchal, and Cheongcheong showed very low populations of BPR and no damages on all treatments. Milyang 30 and Wonpung among them had considerable populations of BPR. Seokwang and 23 others showed high populations and serious damages. Yield increasea(%) with insecticides were low on Gaya(12%), Samgang(29%) and Hangangchal(35%), but very high on Bongkwang(260%), Palgueum(223%), Songjeon(200%), and Guanauk(200%).
