Abstract: <span style="mso-bidi-font-size:9.0pt" lang="EN-GB">The present study reports an efficient protocol for indirect shoot organogenesis and plantlets regeneration of <i>Coccinia grandis</i> (L.) Voigt from nodal explants. The maximum frequency of organogenic callus induction was observed in MS medium supplemented with 0.1 mg/L 1-naphthaleneacetic acid (NAA) and 1.0 mg/L N<sup>6</sup>-benzyladenine (BA). Multiple shoot induction was achieved from the surface of callus on regeneration medium [MS nutrients supplemented with NAA, BA and various concentrations of kinetin (KIN) 0.1-2.0 mg/L]. The highest shoot multiplication (90%) with the increased numbers of shoots (8.7±1.8) and the shoot mean length (8.8±0.4 cm) was achieved on MS medium with 0.1 mg/L NAA, 1.0 mg/L BA and 0.5 mg/L KIN. The regenerated shoots were rooted <i>in vitro</i> on MS medium containing 0.1 mg/L IBA. Plantlets with well developed shoot and root systems were successfully acclimatized (83.5%) and exhibited normal morphology and growth characteristics. </span>
