Melon (Cucumis melo L.) usualy used as a fresh fruit, which contained high vitamin C and in Indonesia melon is one of the favorite fruit. Indonesia is a country that has a high biodiversity. One of the potential strategies in order to improve productivity and quality of crops competitiveness is through plant breeding. This study used melon Aramis from PT East West Seed Indonesia hybrid melon from crosses between 7319 (F) with 7347 (M). The purpose of this study is to determine the phenotype character of melon cultivar Aramis and to detect powdery mildew resistance gene. The research is conducted in Pusat Inovasi Agro Teknologi (PIAT UGM) Yogyakarta and at the Laboratory of Genetics Faculty of Biology, University of Gadjah Mada. Breeding and maintenance is carried out for 6 weeks until the plant grown to enter the age of the harvest. The harvest is later transferred to the Faculty of Biology Genetics and Breeding Laboratory, resistance genes detection  is conducted  by  Sequence Characterized Amplified Regions method (SCARs) using PCR. The results showed negative result of Aramis cultivar on detection of gene resistance to powdery mildew.
