Original Research Paper: The quality characteristics, carotenoids and total phenolic contents of muskmelon cultivars (Cucumis melo L.) were investigated. Four local muskmelons varieties ('Maazoul', 'Galaoui', 'Stambouli', and 'Fakkous') were evaluated for their agronomic characteristics, total carotenoids and total phenolic contents. Significant differences were found between muskmelon varieties in carotenoid and phenolic contents. Total carotenoid content ranged from 1.15 in 'Maazoul' to 12.82 mg kg<sup>-1</sup> FW in 'Galaoui'. The highest phenolic value (474.42 mg kg<sup>-1</sup> FW) was shown by 'Galaoui'. Generally, highest content of carotenoid and total phenolics were obtained for 'Galaoui' variety. In fact, total carotenoid content obtained in 'Galaoui' was more than 12-fold higher than those obtained in 'Maazoul'. This study demonstrates that carotenoid and total phenolic contents were greatly influenced by genotype emphasizing the need to evaluate the muskmelon biodiversity in order to improve its nutritional value.
