We genotyped 119 accessions of Asia Pacific Oryza series Sativae species (Oryza nivara, O. rufipogon Griff., and O. meridionalis) with 29 simple sequence repeat (SSR) markers and looked into variations within and between species. SSR analyses revealed that (1) O. nivara and O. rufipogon share similarities across their distribution but exhibit local scale differentiation, (2) there are eight genetically distinct populations groups that correspond to geographic populations within the three taxa, and (3) O. meridionalis and the Nepalese O. nivara seemed diverged from all the population groups of the series, whereas the Australasian O. rufipogon appeared distinct from the rest of the species.
