Callus Initiation and Regeneration in Tissue Culture of Papaya
Widespread cultivation of papaya is limited because of several factors: their dioecious nature, susceptibility to a large number of viral diseases and lack of commercial methods for clonal multiplication. There have been few attempts in the past to develop a tissue culture propagation system for papaya. Except for the procedure of Litz and Conover (1), others are not ideal as they went through callusing for plantlet formation and are restricted to seedlings (2–5). We report here our preliminary results to develop an ideal system for clonal multiplication of two papaya varieties.
