摘要: 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) 13 samples from Bavaria Hungary. AMOVA $$\upphi$$ -statistics revealed a significant ( $$\upphi_{\rm RT}$$ = 0.23, P < 0.0001) between accessions two other regions. The interpopulation was low PT}$$ 0.13). found greatest distance Hungary (Hoher Flaming, 0.47) lowest Dahmeland Hoher Flaming (both Brandenburg, 0.01). UPGMA dendrogram PCA showed clear disjunction Due outcrossing mating dispersal system, variation within R. is moderately high (87% 76% Hungary). scale suggests lower gene flow with increasing geographical underlines usefulness provenances planting.
