Organogenesis and embryogenesis from diverse explants in pigeonpea (Cajanus cajan L.).

Seed and seedling expiants of pigeonpea were evaluated for organogenesis and somatic embryogenesis. De novo plant regeneration through organogenesis was obtained from mature cotyledons, primary leaves and roots of seedlings. Production of multiple shoots from the cotyledonary node was observed in cultures of whole seeds on 6-benzylaminopurine enriched medium. Somatic embryos were induced from immature cotyledons and embryonal axes, however, well-developed plants could not be derived from these embryos. The regenerants obtained through organogenesis were transferred to the field and grown to maturity.
