Abstract: This study was conducted to develop the clonal propagation technique through in vitro culture using basal stem explants in Phalaenopsis hybrid grown in vitro. The highest frequency of protocorm-like body (PLB) formation was obtained when basal stem explants were cultured on VW medium containing 30 g/L sucrose, 500 mg/L activated charcoal, 150 ml/L coconut water, 1 mg/L NAA, 5 mg/L 2iP and 2.5 g/L gelrite. PLBs transferred to Hyponex medium were regenerated to plantlets. Plantlets transferred to plastic pots containing spagnum moss were developed and successfully acclimatized under greenhouse. Flowers opened in plants regenerated from basal stem explants. The flower was not different from both mother plant and plant induced through clonal propagation of Phalaenopsis hybrid.
