Recently, large plantations have been established in Morocco, to reduce water and wind erosion, rangeland degradation, sand movement and to enhance the restoration of the vegetation cover. However, the plant material utilized has unknown genetic characterization. In addition, several local classifications and morphological descriptions are used. The objective of this study is to analyze the genetic diversity using RAPD markers in a collection of 13 provenances of Moroccan Opuntia ficus-indica (L.). Based on 13 random primers, the result shows that the level of diversity (h) and polymorphism vary according to the provenance. A high genetic differentiation was found between the provenances (Gst=0.29), thus some loci are characteristic of certain provenances. These results can be used to characterize genetic resources of Morocco cactus pear, and to initiate a program of genetic improvement and selection.
