The aim of this study was to compare the major pomological and antioxidant properties of fruits that were comparatively studied in wild blackberries from natural habitats and commercially important varieties grown in the Una – Sana Canton (Bosnia and Herzegovina): Navaho, Jumbo and Loch Ness. It also aims to point out the potential superiority of the wild forms, how they are rich in vitamin C, phenol and anthocyanins, so that they would be considered as a potential source of natural antioxidants. It was found that, according to morphometric characteristics of the fruit, the fruits of wild blackberry exhibited significantly lower values, while the chemical composition of the fruit showed superiority. The highest value of vitamin C was found in wild species Rubus fruticosus L. (23.06 mg/100g). The high content of anthocyanins (238.7mg/100g) was found in Navaho blackberry. In the case of the examined blackberry genotypes, species or variety was not a factor that affects the content of phenol and anthocyanins in the fruit, so it can be assumed that the original features of these components have not been lost during the selection and breeding of new varieties. The variety Jumbo proved to be a variety with a very large fruit, and thus can be recommended to blackberry growers because of its attractiveness and the possibility of achieving high yields. Wild blackberry genotypes constitute the genetic potential of particular importance for the conservation of biological diversity of certain areas, as well as for the selection and breeding of cultivated fruit.
