Abstract

We investigated the genetic differentiation of Rosa canina at regional and continental scales to delineate provenance regions for seed collection. Using RAPD technique, we examined eight populations in Brandenburg (Germany) and 13 samples from Bavaria and Hungary. AMOVA and \(\upphi\)-statistics revealed a significant differentiation (\(\upphi_{\rm RT}\) = 0.23, P < 0.0001) between accessions from Brandenburg and the two other regions. The interpopulation differentiation in Brandenburg was low (\(\upphi_{\rm PT}\) = 0.13). We found the greatest interpopulation distance between Hungary and Brandenburg (Hoher Fläming, \(\upphi_{\rm PT}\) = 0.47) and the lowest between Dahmeland and Hoher Fläming (both Brandenburg, \(\upphi_{\rm PT}\) = 0.01). UPGMA dendrogram and PCA showed a clear disjunction between Brandenburg and other regions. Due to the outcrossing mating and seed dispersal system, the genetic variation within R. canina populations is moderately high (87% for Brandenburg, 76% for Bavaria and Hungary). The significant genetic differentiation at the continental scale suggests lower gene flow with increasing geographical distance and underlines the usefulness of regional provenances for planting.
