Coconut has a wide range of applications from culinary to industrial areas. Loss of coconut trees due to the devastating effect of deadly diseases and the natural aging of the plants demand rejuvenation of orchards with elite seedlings. A conventional breeding program is not sufficient to meet the growing need for healthy planting materials. However, in vitro culture studies can pave the way for mass multiplication. In this study, the effect of TDZ on sliced mature embryo explants through direct organogenesis of coconut var. Chowghat Orange Dwarf (COD) was investigated. The treatment Y3 + 150µM TDZ recorded highest shoot induction (90.91 %) and shoot regeneration (72.73 %). A higher concentration of TDZ reduced the frequency of shoot organogenesis. Well-grown shoots were transferred to rooting media and plantlets were subjected to primary hardening.
