An efficient in vitro micropropagation protocol was developed for direct shoot growth of interspecific Cucurbita hybrid variety using shoot-tips of 5-day-old explants. The excised shoot-tips were cultured on Murashige and Skoog (MS) medium containing two plant growth regulators (6-benzyladenine and naphthaleneacetic acid) with various combinations and concentrations for the study of shoot induction. The best condition for shoot growth was with 3 mg l-1 6-benzyladenine (BA) in MS medium. The shooting frequency was 84% and five shoots were obtained from each explant after 30 days of culture. Shoots (1-1.5 cm length) were rooted most effectively in 1 mg l-1 indole-3 butyric acid (IBA)-supplemented MS medium. The highest root formation rate was 93% and all rooted shoots were transplanted into soil.
