| Summary: | Coconut is one of the major plantation crops of India and the demand for elite seedlings is exorbitant. In this study,
superior mother palms of Chowghat Orange Dwarf (COD) which is not completely homozygous were identified based
on Phenotypic Co-efficient of Variation (PCV), Genotypic Co-efficient of Variation (GCV), heritability and genetic
advance of morphological traits for applications in crop improvement. Explants from superior palms viz., mature
embryos (whole/sliced) and shoot tips (whole/sliced), were used for direct organogenesis. Among these, sliced shoot
tips (4 slices) in Y3 basal + 200 µM Thidiazuran (TDZ), recorded highest shoot induction (350 %) and regeneration
frequency (325%) at 30 Days After Inoculation (DAI) and 60 DAI respectively than sliced embryos (4 slices) which
recorded lesser shoot induction (170 %) and regeneration frequency (125%). This is the first study that demonstrates
shoot tips as one of the potential explants for in-vitro production of quality coconut seedlings.
