An efficient system was developed for indirect plant regeneration from in vitro-derived leaf and internode explants of Hoya wightii ssp. palniensis. Maximum percentage of the organogenic callus was obtained on MS medium supplemented with NAA (1.0 mg/l) and 2,4-D (2.0 mg/l). The best shoot bud induction was observed on MS medium with BA (1.0 mg/l) +IBA (0.5 mg/l). The coconut water (15%) was better, resulting in a differentiation of the shoot initials in to well-developed shoots. The elongated
