Abstract: Capparis decidua is a rangeland plant species growing in isolated regions in Saudi Arabia. The population in Rawdhat Khuraim was noticed to suffer from lack of new regeneration, in addition to excessive grazing which may reduce the size of the population and reduce the genetic variability. RAPD markers were used to study genetic diversity in this population and a control population. Two criterion were used to study the genetic diversity in population in Rawdhat Khuraim. The first was cluster analysis and genetic distance, and the second is the percentage of polymorphic alleles. Cluster analysis showed that coefficient of similarity within Rawdhat Khuraim population (84-93%) is a lot larger than between Rawdhat Khuraim and the control population (77%). In addition, the percentage of polymorphic alleles in population of Rawdhat Khuraim was 45.8, which is within the range of other endangered plant species. This indicates that the population in Rawdhat Khuraim is iso1ated, suffering from narrow genetic base and of a particular conservation concern.
