RAPD analysis was used to fingerprint 29 genotypes of Cereus species and examine their genetic diversity. Some modifications were made to the DNA extraction procedure with a view to assuring higher DNA yield and purity. A dissimilarity matrix and dendrogram were constructed to help visualize genetic relationships between different genotypes. The results show that C. peruvianus has only a limited genetic base and that further improvement of this crop may require the introduction of additional germplasm into breeding programmes. RAPD markers were shown to be a valuable tool for clone identification in Cereus species and for determining genetic relationships.
