Abstract

The standard Murashige and Skoog (1962) culture medium was proven effective for initiation of meristem in cultures of cocoyam (tannia; Xanthosoma sagittifolium cv. Rabess) but was found not to be so useful for plantlet regeneration. However, when cultures at 6-8 weeks old were transferred to an amended medium /with the exclusion of benzylaminopurine (BAP)/ calli formation was high along with organogenesis, resulting in extensive shoot and root development. Plantlet regeneration from meristems was achieved within 16-20 weeks. There was no significant variation in plant morphology of plantlets regenerated using this two-step production system.
