The adaptation test of hybrid melon variety candidates was conducted in order to choose melon candidates for release as varieties. The main objective of this research was to select and test several candidates for hybrid melon varieties in three locations on the island of Madura, Indonesia. This research was conducted in three districts on Madura Island, i.e., Bangkalan Regency (longitude: 112044 E; Latitude: 7007 S; altitude: 5 m), Sampang Regency (longitude: 113008 E; Latitude: 7007 S; altitude: 25 m), and Sumenep Regency. (longitude: 113045 E; Latitude: 7002 S; altitude: 50 m). The planting materials used were nine genotypes of melon plants consisting of six hybrid melon variety candidates, i.e., MH-17, MH-29, MH-33, MH-37, MH-40, MH-42, and three comparison varieties, i.e., Anvi variety. Oren variety and Madesta variety. This research used a randomized complete block design with genotype as a treatment. The results showed that Genotypes MH-17 and MH-33 are recommended to be released to farmers because they had the characters of short harvest age (<70 days), high fruit weight (> 2,000 g), and high sugar content (> 10 0Brix) and had the same or greater character than the three comparison varieties (Anvi, Oren and Madesta).
