Abstract
Melon necrotic spot virus (MNSV) is a very destructive disease to melon (Cucumis melo) plants. A MNSV was isolated from melon leaf showing necrotic spot symptoms at the plastic house in Naju, Korea in 2009. The isolate, designated as MNSV-Me, was identified and characterized by biological responses on several host plants, immuno captured RT-PCR and partial nucleotide sequencings of the genome. To evaluate MNSV-Me resistance in melon, thirty-five melon cultivars were mechanically inoculated on the cotyledon of the seedlings with the virus. MNSV-Me produced necrotic spots on the inoculated leaves of the all melon cultivars tested. Twenty-five cultivars were susceptible to the virus and they showed systemic necrotic spots on the leaves and/ or necrosis longer than 3 cm in length on the stems within about forty days after inoculation. Five cultivars gave moderate resistance, no symptoms on the upper leaves but necrosis on the stem shorter than 3 cm in length. In an evaluation of MNSV-Me resistance in melon cultivars, ``Elstitan``, ``Elsluxery``, ``Betalichihage``, ``Betalichi`` and ``Womderfulhagae 1st`` were found to have resistance by showing only faint necrosis on their stems.
Key Words: Melon, Melon necrotic spot virus, MNSV, Resistance
