Abstract A variety of DNA probes was used to screen a diverse set of oil palm accessions in order to identify markers with a utility in genotype discrimination. This survey included samples of the commercial oil palm native to Africa (Elaeis guineensis Jacq.), the closely-related South American species [E.oleifera (HBK) Cortes] and inter-specific hybrids of the two. Of 106 major chloroplast bands none showed differences between E. guineensis and E. Oleifera. Mitochondrial and ribosomal probes were more informative inter-specifically (the former allowing identification of the maternal inheritance of mitochondria) and may be useful in hybrid breeding programmes; however, they were unable to identify polymorphism within E. guineensis. In contrast, low-copy nuclear genomic clones were able to identify intra-specific variation, though in most cases they revealed a relatively small number of allelic variants. One DNA probe showed a much larger number of band variants, revealing ten patterns amongst 13 E. guineensis accessions, and should prove useful in genetic fingerprinting and evaluation of oil-palm germplasm collections.
