The purpose of the study was to compare basic fruit chemical composition of four highbush blueberry cultivars: ‘Spartan’, ‘Bluecrop’, ‘Jersey’ and ‘Blueray’. The plants were grown on plantation near Szczecin in the years 2001-2003. Basic chemical composition of fruit including total ash, crude fibre, total nitrogen, soluble solids, titratable acidity, dry weight and total polyphenol content was determined. On average, ‘Spartan’ berries showed the highest total ash, total nitrogen and soluble solids content. ‘Bluecrop’ berries had the highest total polyphenol content, the berries of ‘Jersey’ the highest dry weight content and that of ‘Blueray’ the highest total acid content. The most considerable seasonal variations in fruit chemical composition of the cultivars were observed for soluble solids and titratable acidity was concerned.
