Molecular diversity of hops (Humulus lupulus L.)

We analyzed genetic structure and diversity among hop genotypes using 25 new microsatellite markers and a set of 67 wild and cultivated hop accessions, well representing the available diversity among currently and historically used lines. Model-based clustering (Structure) placed the accessions into five gene pools that correspond to major breeding groups and to accessions showing mixed origin. A phylogenetic clustering shows good agreement with pedigree information and five gene pools, and further assigned eight accessions omitted from Structure analysis into two additional gene pools. The seven defined gene pools were best represented by 50 accessions. The cultivated hops differ significantly from the wild ones, although most of the variability was found within groups. Molecular variances within groups of cultivated and wild hops were homogeneous, suggesting that a similar level of molecular variability is found in both groups of accessions. Core sets of cultivated hop accessions that capture maximum allelic richness were defined, generally including hop cultivars of 'mixed origin' that combine alleles originating from different gene pools and thus have the greatest allelic richness.
