Breadfruit is generally vegetatively propagated using root shoots or root cuttings which makes distribution of plant material over long distances difficult. In vitro (tissue culture) propagation offers a method by which breadfruit can be more quickly propagated and distributed and meet international quarantine requirements. This two-year project, conducted by Ms. Cynthia Nazario, a graduate student at the University of Hawaii, Department of Tropical Plant and Soil Sciences, was completed in 2003. Additional studies are needed to determine the best methods to mass-propagate breadfruit in vitro and to establish tissue-cultured plants in greenhouse and field conditions.
