Polymerase Chain Reaction (PCR) analysis based on Internal Franscribed Spacers (ITS) and Random Amplified Polymorphic DNA (RAPD) were carried out on sixteen provenances of Faidherbia albida
currently growing in a provenance trial in semi-arid Baringo district in Kenya. The objectives of the study were to: (i) determine the phylogenetic relationship among the 16 provenances in order to establish the species centre of origin, and (ii) determine the extent of genetic diversity in F. albida
using PCR markers. ITS data did not produce any consistent regional or geographic pattern. RAPD data produced a dendrogram clearly grouping the provenances into Western, Southern and Eastern African regions. The study revealed the utility of RAPD markers in understanding geographic variation and phylogenetic relationships among F. albida
populations in Africa.
