title: Genetic differentiation of three endangered wild roses in northeastern Germany: Rosa inodora Fries, Rosa sherardii Davies and Rosa subcollina (H. Christ) Keller.
abstract: Because of increased interest in the use of local provenances for restoration or landscaping projects, information about the genetic differentiation of plant species is required to delineate provenances for seed collection. To obtain information about population distinctiveness of endangered Rosa species occurring in Brandenburg (northeast Germany), we investigated the genetic differentiation of Rosa inodora, R. sherardii and R. subcollina using RAPD markers. All three species were uncommon in our study region. Φ-statistics, estimated by amova, revealed a low interpopulation differentiation for R. inodora (Φ(PT) = 0.19, P < 0.0001) and higher values for R. sherardii and R. subcollina (Φ(PT) = 0.29 and 0.30, P < 0.0001). UPGMA dendrograms and NMDS showed clear spatial differentiation for all species and a correlation between geographic and genetic distances. Due to predominantly high values of genetic differentiation and spatial patterns of ordination, we suggest small provenance regions for endangered Rosa species for seed collection.
