Abstract
Fifteen Hordeum species and subspecies belonging to groups with different genomes were studied usingPCR-based markers to establish phylogenetic relationships within the genus. Two hundred and seventeen RAPDand STS markers were used to calculate genetic distances and construct phylogenetic trees. The phenetic analysisclearly separated the primary gene pool, represented by H. vulgare ssp. vulgare, H. vulgare ssp. vulgare convar.vulgare f. agriochriton and H. vulgare ssp. spontaneum, from the secondary gene pool, represented by H.bulbosum and the tertiary gene pool, represented by American wild barleys and H. bogdanii. Data obtained fromPCO analysis are in complete agreement with taxonomic classifications proposed previously, which werecomparisons of numerous morphological, cytological and reproductive characters.
