Phenotypic observations of the mother trees to assess clinal variation within the species (CNSF and FRIN);

*
Investigation of the genetic diversity of P. biglobosa throughout its natural range, by establishing the inheritance of 15-20 enzymatic systems using electrophoresis techniques : a Ph.D. project supervised by Dr. Hélène Joly (Centre Technique Forestière Tropical, France) and Prof. van der Maesen (Wageningen Agricultural University, the Netherlands),

*
Investigation of population status at study sites in protected areas and intensively farmed areas : a Ph.D project supervised by Dr. John Hall (School of Agricultural and Forest Sciences (SAFS), University of Wales, Bangor, UK);

Development of vegetative propagation and tissue culture techniques, and induction of precocious flowering (SAFS);

*
A socio-economic survey to elicit indigenous knowledge of the management and utilisation of the tree by the local people, co-ordinated by SAFS;

*
Field investigations of nitrogen fixing capability and mycorrhizal associations, and controlled greenhouse experiments using isolates of root symbionts (SAFS);

*
Development of multi-trait selection criteria using information gained from phenotypic observations, the socio-economic survey and determination of heritable traits through electrophoresis techniques (SAFS);
