Random amplified polymorphic DNA analysis in Hordeum species.

Random amplified polymorphic DNA analysis was performed by applying a set of 13 arbitrary 10-mer primers to 19 Hordeum species and subspecies. High levels of variation in fragment pattern were observed both within and among species with most of the primers used. Genetic similarities between accessions and species were calculated from the fragment patterns. The resulting phenograms confirmed previous relationships among the Hordeum species.
