초록

흰가루병과 뿌리혹선충병은 박과작물에 발생하는 매우 중요한 병이다. 본 실험은 시판된 국내 주요 박과작물(오이 21품종, 수박 9품종, 참외 7품종, 멜론 2품종)을 이용하여 흰가루병과 뿌리혹선충병에 대한 저항성을 평가하기 위하여 수행하였다. 흰가루병 조사는 정식 60일 후 조사하였다. 21개의 오이 품종 중 '강력삼척'과 '선호백침 다다기'는 중도저항성을 나타냈고 나머지 오이 품종은 모두 감수성이었다. 수박 품종은 모두 감수성을 나타냈다. 참외 품종에서는 저항성을 나타내는 품종은 없었으나 'PMR터보'와 'PMR빅토리' 2개 멜론 품종은 저항성을 나타냈다. 뿌리혹선충병은 유묘에 접종 45일 후 병 발생을 조사하였다. 오이 품종 '백봉다다기'가 중도저항성을 나타냈고 다른 20개의 오이 품종은 모두 감수성이었다. 수박 품종은 '달고나꿀'이 저항성이었으며 다른 품종은 중도저항성이거나 감수성이었고, 조사된 모든 참외와 멜론 품종은 뿌리혹선충병에 대하여 감수성이었다. 이상의 결과를 근거로 흰가루병 및 뿌리혹선충에 저항성인 품종은 박과작물의 유기재배에 이용할 수 있을 것이다.

Powdery mildew and root-knot nematode are very important diseases occurred in cucurbits. This study was conducted to evaluate the resistance of commercial cucurbit cultivars (21 cultivars of cucumber, 9 cultivars of watermelon, 7 cultivars of oriental melon, and 2 cultivars of melon) to powdery mildew and root-knot nematode. At 60 days after transplanting, disease severity of powdery mildew of commercial cucurbit cultivars was investigated. Two cucumber cultivars, 'Gangryeogsamcheok' and 'Sunhobaegchimdadagi' were moderately resistant but the rest of cucumber cultivars were susceptible to powdery mildew. All examined watermelon and oriental melon cultivars were susceptible to powdery mildew, while two melon cultivars ('PMR Turbo' and 'PMR Victory') were resistant. At 45 days after inoculation of seedlings, disease severity of root-knot nematode of commercial cucurbit cultivars were investigated. One cucumber cultivars, 'Baegbongdadagi' was moderately resistant and the others were susceptible to root-knot nematode. In case of watermelon, 'Dalgonakkul' was resistant and the others were moderately resistant or susceptible to root-knot nematode. All examined oriental melon and melon cultivars were susceptible to root-knot nematode. On these results, we recommend that resistant cultivars to powdery mildew and/or root-knot nematode will be more suitable in cultivation of cucurbits for organic farming.
