Isolation and culture of protoplasts of pigeonpea (Cajanus cajan L.)

Summary High yields of protoplasts were obtained from leaves of aseptically grown plants and calli originated from different explants, in several cultivars of Cajanus cajan L. The protoplasts divided to form cell clusters in modified KM 8p medium and developed to protocolonies after dilution with liquid Caboche's medium within three to four weeks of culture. The protocolonies proliferated to form green calli on solid Caboche's medium. No shoots or plants were obtained.Abbreviations BAP 6-benzylaminopurine - NAA -napthaleneacetic acid - 2,4-D 2,4-dichlorophenoxyacetic acid - Kin kinetin - Zea zeatin - Adn S adenine sulphate - GA ₃ gibberellic acid
