In spite of the fact that much needs to be done to exploit the large variability in the various world collections using traditional methodologies, tissue culture techniques are already making an impact on cassava breeding. This paper reviews the present status of cassava tissue culture and examines its possible uses, potentials and limitations.  aCassava breeding1 aCAPPADOCIA, M.
