dct.abstract Five wild sea buckthorn populations in Finland were studied using 8 SSR markers to reveal genetic diversity within and among populations. Population samples were collected from four different locations on mainland and one from the Åland Islands. Allelic data obtained from SSR markers were subjected to statistical analysis and AMOVA, and rarefaction was used to correct effects of uneven population sample sizes on some population diversity indices. Results showed moderate to high genetic diversity levels, as mean HE of all populations was 0.55 and HO 0.50. Most populations showed larger observed heterozygosity levels than expected, one showed equal amounts and one population showed lower heterozygosity levels than expected. Most genetic variation of populations was found within individuals across populations (84%) and only some among populations (16%). A weighted neighbor-joining phylogenetic tree showed only some clustering based on populations. The results of this study show, that there is mentionable diversity in Finnish wild sea buckthorn populations, and that populations are only moderately differentiated. This information can be beneficial particularly in sea buckthorn breeding efforts, but also from a possible genetic resources’ and conservation standpoint. en
