Analysis of Genetic Relationships Between Wild Roses (Rosa L. Spp.) Growing in Turkey

RosaL. taxa are dominantly used for horticulture, food, medicinal, ornamental and aesthetic purposes. Rosa is represented with approximately 200wild species in the world. The number of natural Rosa species in Turkey is reported as about 31.Rosa species are widely distributed in all regions in Turkey. In this study, RAPD and ISSR markers were applied to assess genetic diversity and genetic relationships among 27species of Rosa. The UPGMA cluster was constructed using acombination of data from RAPD and ISSR markers. The dendrogram revealed two main clusters. Each cluster was divided into subgroups. This investigation showed that genetic distance was relatively significant among the species. As the results of the study close genetic relationships were found between evolutionary relations, morphplogical properties, and phytogeographical distributions of the Rosa species, The results also propose that RAPD and ISSR markers are useful tools for indicating genetic relationships among Rosa genotypes.
