Study of some phytochemical and morphological characteristics of dog rose (Rosa canina L.) fruit in north of Iran

In this investigation some chemical and morphological properties of dog rose fruit in 10 regions of north Iran were measured. Results showed significant difference between traits in studied regions. Beta-carotene ranged between 0.05 – 0.323 (mg/g FW). Total soluble carbohydrate varied from 5.9 – 23.3%. The highest content of total anthocyanin 23.7 and the lowest was 7.71(mg/L cyanidin-3-glucoside). The highest and lowest amount of TSS in regions under study was 15.72 and 34.9%, respectively. GGE biplot method used for studying effect of different regions on chemical and morphological properties. IR56 accession had highest amount of beta-carotene according to the polygon. The highest content of and total anthocyanin obtained from IR51. Pearson’s coefficients showed that fruit weight had significantly correlation with fruit flesh. Fruit length had significantly correlation with fruit width. Also Total soluble carbohydrate correlation with total anthocyanin and TSS was significant. Obtained results from this study could be used in the future breeding program of dog rose.
