Abstract

An efficient protocol was developed for in vitro plant regeneration and multiplication through callus culture in pointed gourd. Among the explants, highest percentage of cotyledon explants (92.00%) produced callus when this explant cultured in MS medium supplemented with NAA (0.1, 0.5, 1.0, 1.5, and 2.0 mg/l) and 2, 4-D (0.1, 0.5, 1.0, 1.5, and 2.0 mg/l). The highest number of shoots per explant was observed in MS + 0.5 mg/l BAP + 0.5 mg/l NAA followed by 1.0 mg/l BAP + 0.5 mg/l NAA when inter-node derived callus cultured in MS medium. Among the explants derived calli from leaf, inter-node and cotyledon in in vitro regeneration study, inter-node appeared as the most suitable explant for callusing and plant regeneration. The best response towards root induction was achieved on half MS medium supplemented with 0.5 mg/l NAA. The regenerated plantlets were successfully established in prepared earthen soil pot.
