Resumo: The interest in exploring the European wild blackberries, resulting of the high potential for health, has led the researchers to consider possible introductions of this germplasm in breeding programmes. As Portugal has a large number of these species, trials have been conducted in order to characterize agronomic, quality and phytochemical traits of some of this material. On the first trial, the agronomic characterization, only two R. henriquesii and R. sampaioanus showed acceptable vegetative and productive characteristics. The cold trial produced significantly different percentages of bud break in tertiary canes and caused an effect of earliness, showing higher production. In the third trial, the technique of pruning the clusters in R. radula and R. henriquesii, concluded not to be useful increasing the fruit size of these species. In the last trial, it was demonstrated the phenotypic variability of the species R. ulmifolius. Were still performed three characterizations, the species with the highest content of total soluble solid (TSS) was the R. radula “pruning” and R. henriquesii. Total acidity and pH showed no significant differences. Concerning phytochemical characterization, the R. henriquesii and R. radula showed the highest content in phenols, and R. vigoi in antioxidant capacity. Chromosome counting has shown that the variety “Sommer” is diploid.
