Melon (Cucumis melo L.) belongs to Cucurbitaceae. Melon has high potential to be developed as main horticultural product in Indonesia. Melon is one of important foreign exchange and is the fifth biggest horticulture commodity in Indonesia. One of the problems in melon farming is mosaic disease caused by Kyuri green mottle mosaic virus (KGMMV). KGMMV infection reduces the quality and the amount of melon production. Melon farmers suffered a significant financial loss. Melodi Gama 3 (MG3) is a high yielding melon cultivar from the Genetics Laboratory, Faculty of Biology, Universitas Gadjah Mada. The use of genetically resistant melon cultivar has beneficial outcome for agriculture sector. The aim of this research was to study the resistance’s inherintance to KGMMV in MG3 melon cultivar. Two cultivars of MG3, MG3|5and MG3|8, were cultivated in the greenhouse. MAI, Glamour, Ladika, and Action melon cultivars were used as references. Resistance of KGMMV was analyzed by symptom observation and serological detection using Double Antibody Sandwich Enzyme Linked Immunosorbent Assay (DAS-ELISA). DAS-ELISA result analyzed further to establish resistance category. Description to melon cultivar phenotype variation was done. The result of this research indicates that MG3 melon cultivar is tolerant to KGMMV. The decrease of MG3 optical density was directly related with the lowering of KGMMV symptoms. The character of tolerance to KGMMV was inherited from Melodi Gama 1 (MG1) cultivar.
