Resultados preliminares sobre la caracterización molecular de palma de aceite mediante marcadores microsatélites.

A molecular characterization of wild and commercial African oil palm (Elaeis guineensis Jacq) and of American oil palm (Elaeis oleifera) belonging to commercial plantations was performed, using microsatellite markers. The aim was to estimate possible differences and/or genetic similarities among the different materials. The analysis of the information was performed by generating a similarity matrix among individuals using the genetic similarity coefficient of Nei and Li (1979). With the resulting data a dendrogram was built using the upgma grouping method. The dendrogram and the multiple correspondence analysis, made with samples of E. guineensis from different commercial seed producers show the formation of three groups. Groups A and B clustered materials produced by commercial seed producers in Malaysia, France, Costa Rica and Colombia, showing a high degree of genetic similarity. The group C is made up of interspecific hybrids (OxG). The materials E. guineensis from the Republic of Cameroon, showed a genetic similarity index 55por ciento, indicating a high genetic variability, but a clear association between geographical origin and the resulting groups could not been established. In the dendrogram and principal coordinate analysis of the samples of American oil palm E. oleifera, the conformation of two groups associated with their geographical origin site was observed. The materials presented site-specific alleles and low genetic similarity (44por ciento) among them.
