“…Cvrčková et al 2015). In contrast, several SSR-based studies dealing with population genetics in peripheral populations of silver fir and its related species appeared in this time period (Belletti et al 2017, Dalmaris et al 2022, Sancho-Knapik et al 2014, Teodosiu et al 2019). Thus, conclusions about diversity gradients and the population genetic structure of silver fir in Central Europe are mostly based on older studies applying isozymes (Breitenbach-Dorfer et al 1997, Konnert and Bergmann 1995, Lewandowski et al 2001, Liepelt et al 2009.…”

Central European populations of silver fir (Abies alba Mill.) grow under a relatively wide amplitude of environmental conditions. Assuming that forest tree stands are locally adapted, the use of forest reproductive material from sites with limited water availability is expected to increase drought tolerance in future forests. At the same time, genetic diversity is of utmost importance as the basis of adaptation to a changing environment. Currently, a selection of potential sources for climate-smart reproductive material of silver fir is under way in Southern Germany. It is based on a multidisciplinary approach elucidating the genetic variation, site conditions, as well as tree resilience based on a dendroecological approach. The analysis encompasses a large number of stands representing the whole range of the species’ ecological requirements. The population genetic analysis based on molecular markers (nuclear microsatellites) provided important information concerning the gene pool of the species in Southern Germany. On one hand, it revealed genetic differentiation and transition zones between western and eastern clusters. On the other hand, the results indicated gradients and regional variation of genetic diversity. These patterns can be explained by post glacial recolonization and the peripheral character of the species at the northern limit of its distribution. Together with the outcomes of the site condition and dendroecological approaches, the results of the genetic analysis will be used to inform future provenance recommendations.
