Cucurbita moschata is an important and popular vegetable, used throughout the world due to its taste, nutritional and medicinal values. Plant growth hormones play an important role in the growth and development of crop plants. Callus development of Cucurbita moschata was accessed produced from cotyledon, leaf, hypocotyls and root under the application of auxins dichlorophenoxyacetic acid (2,4-D) and cytokinins 6-Benzylaminopurine (BAP) with different concentrations. It was found that 1.5mg/L BAP+1.5mg/L 2,4-D and 0.5mg/L BAP+1.5mg/L 2,4-D combination was best for callus development from cotyledon, as both gave a callus index of 300 but the time for callusing was 9 and 10 days respectively vs. 2,4-D and BAP (3 mg/L) for callus induction by leaves, 2mg/L BAP+1.5mg/L 2,4-D for callus induction from hypocotyl and from root the combination of 1.5mg/L BAP +3mg/L 2,4-D produced the best results. It was suggested form the results that the combination of optimum concentrations (1.5-3mg/L) of BAP and 2, 4-D may be useful for developing higher callus mass in short time.
