A rapid and efficient protocol is outlined for in vitro propagation of muskmelon(Cucumis melo L.) Shoot tips, nodal segments and cotyledonary nodes from invitro grown seedlings were used as explants. The explants were inoculated on MS medium fortified with different combinations and concentrations of growthregulators viz., BAP, NAA, GA3 and IBA for multiple shoot regeneration.Effective result was found on MS medium supplemented with 2.0 mg/l BAP, inwhich 90% and 70% cultures induced multiple shoots from nodal segments andshoot tip explants, respectively. Whereas, 70% cultures of cotyledonary nodeswere found to induced shoots on MS medium with 1.5 mg/l BAP + 0.1 mg/l GA3. In vitro regenerated shoots were subcultured on half strength MS mediumsupplemented with different concentrations of IBA and NAA for successful rootinduction and the effective result (up to 70%) was found in medium with 1 mg/lIBA. Well rooted in vitro grown plantlets were acclimatized in sandy soil, whereas 70% plantlets survived
