'Prince Melon' (Cucumis melo var. reticulatus Naud × Cucumis melo var. makuwa Mak.) was analyzed to determine the relationship among refractometer index, sugar content and volatile compound evolution during developmental and postharvest stage of the fruit. All the components were increased during development up to 34 days after anthesis. Among sugars, only sucrose increased parallel with total sugar and refractometer index. Refractometer index and total sugar in early picked fruit (20 days after anthesis) and in matured fruit (27 days after anthesis) were almost constant during storage at 20℃, although sucrose concentration of mature fruit increased at the 5 th days from the start of storage and then decreased gradually toward 15 days from the start of storage. Volatiles, mainly esters, emanated very little from early picked fruit at harvested day, but the production increased in significant level during the storage. Volatile production from mature fruit was already high at harvesting time and fluctuated that level depend on individual ester during storage. The correlation between refractometer index and volatiles production was high in developing stages, while the correlation was very poor during storage at 20℃ in both early picked and mature fruit. These results revealed that volatile would become good indicator for fruit quality at picking time without any destruction. However, volatile can not be a good indicator for storage period and also on the shelf in retail market.
