Cucumis melo L. is one of the most economically important horticultural crops worldwide. However,   low plant regeneration frequency of this plant during genetic transformation is  the  major hurdle for  applying biotechnological approaches. Hence, this study aimed to evaluate the effect of 6-benzyladenine (BA), cefotaxime (CTX), kanamycin (KAN), and indole-3-acetic acid (IAA) on the regeneration of cotyledonary petioles generated from 6-day-old in vitro grown seedlings. Results showed that  application of 1.5 mgl-1 BA plus 250 mgl-1 CTX and 1 mgl-1 BA with 1000 mgl-1 CTX formed the most efficient media for plant regeneration. The highest callus production was recorded on medium containing 1 mgl-1 BA with 250 mgl-1 CTX and 1.5 mgl-1 BA with 750 mgl-1 CTX. Medium containing 500 mgl-1 CTX plus 0.1 mgl-1 IAA  efficiently  induced both root \ and leaf formation. All regenerated plants were died by adding   100 mgl-1 kanamycin therefore this level considered as threshold level for kanamycin application.. Overall, the results indicated that presence of BA plays an essential role for melon regeneration and cefotaxime can be considered as an auxiliary agent.
