Abstract
Dog rose (Rosa canina L.) is a cosmopolitan plant species that due to its nutritional, medical and cosmetic values deserves more attention. Dog roses are cultivated in Croatia on very small scale and most of the rose hip used in the domestic processing industry is imported. In this study, three dog rose F1 progeny populations developed from selected plants collected in Korčula, Malešnica and Prigorje Brdovečko, originating from two climatic regions (P1 - Mediterranean and P2 and P3 - continental) have been studied as a part of a field experiment for two growing seasons, in order to assess the level of genetic variability for pomological and agronomic traits. In addition, genetic variation within and among examined three dog rose populations has been assessed using 6 polymorphic SSR (Simple Sequence Repeats) markers. The highest variability, as well as the most desirable agronomic traits were found within the P3 population, while the lowest ones were present in the P1 population. Most desirable properties and highest values for commercially important traits were detected in the genotype RC29 (P3). Molecular data was sufficient to separate three studied populations but not all individuals within the populations. Through selection and hybridization of perspective genotypes of dog roses from Croatia, it would be possible to create clonally propagated varieties suitable for commercial cultivation.
