Seventeen SSR markers were selected randomly for molecular characterization/fingerprinting of two accessions of Arachis diogoi and three accessions of A. chiquitana to ascertain whether the morphologically different A. chiquitana accession ICG 11560 may be an accession of A. diogoi (=A. chacoense). Two accessions of A. chiquitana, ICG 13181 and ICG 13241, formed a distinct group. A. chiquitana accession ICG 11560 did not group closely with the other A. chiquitana accessions, but showed closer relationship with them than with the A. diogoi accessions ICG 4983 and ICG 8962. The two accessions of A. diogoi, ICG 4983 and ICG 8962, grouped together and were separated from the group formed by section Procumbentes members. These results show that A. chiquitana accessions in general and ICG 11560 in particular are not related to accessions of A. diogoi. In another experiment, similar results were obtained when RAPDs (random amplified polymorphic DNAs) were used to distinguish wild Arachis species.
