Abstract: Blueberry is currently cultivated in Italy on a relatively small scale, but - as in other parts of the world - its production is increasing. It is highly adapted to the Alpine regions and in Trentino (Northern Italy) it represents one of the most representative commercial crops. In general, the most important species in commercial orchards are V. corymbosum, V. angustifolium and in a low percentage of V. ashei. The high concentrations of antioxidants and other beneficial health compounds in blueberries have increased the demand for this crop among healthconscious consumers and may further increase in the near future. The development of DNA-based markers in blueberries has facilitated species distinction and cultivar identification, allowing the production pipeline to be more precise and consistent, with particular regard to plant production and subsequently fruit quality for consumption. Moreover the development of a good analysis method permitted the stilbene content determination in different Vaccinium spp and varieties. We have assessed the diversity and relationships of accessions of blueberry derived from different European and extra-European countries using various fruit and plant morphological descriptors, fruit biochemical profiles and 13 highly polymorphic genomic SSRs. Different statistical analysis were conducted on the different data types (genetic, morphological, biochemical) to determine the different clustering structures. These results were compared to determine the most representative structure of the varieties/species under analysis. Assessment of the diversity and relationships of the cultivated species facilitates the establishment of conservation strategies, implements the study of blueberry crop evolution and increases the quality production process. Keywords: blueberry, SSRs, germplasm, stilbene, morphological and biochemical descriptors Type of presentation: Poster Topics: Germplasm collections and molecular characterisation. . &.
