Abstract
Oil palm Elaeis guineensis Jacq is an important edible oil producing crop. The world;s largest palm oil producer Malaysia collected germplasm materials from Africa and South and Central America in order to enrich the gene pool. In this study a total of 687 accessions belonging to eleven African countries and Deli dura from Malaysia were screened with AFLP markers using eight primer combinations. There were 377 bands of which 93.4 were polymorphic. Cameroon palms showed the highest estimated mean genetic diversity 6.65 while Deli dura showed the lowest 3.63. A higher proportion of the total diversity was observed within populations 55 than between populations 45. Similarly genetic diversity within countries 71 was higher than between countries 29. Dendrograms based on three similarity matrices demonstrated the same pattern of grouping except for a few countries. The results supported the Nigerian origin of oil palm. Comparatively genetic diversity was high in Nigeria and gradually decreased for Senegal and Gambia and also for Angola and Tanzania. This study confirmed the low genetic diversity in Deli dura populations. Results also suggested that Deli dura might have originated from Nigeria more specifically from population N-12. Madagascar oil palm seemed to possess a large amount of variability 6.39.
