    Abstract:
    This study evaluated 20 advanced selections, derived from a strawberry interspecific backcross program, and their parents for fruit weight, commercial yield, acidity, sugar content, antioxidant capacity, and phenol and anthocyanin contents. Phytochemical profiling analysis was performed to determine the compositional characteristics of the improved selections in comparison with their parents and an important commercial variety ('Elsanta'). Advanced selections showed substantial improvement for agronomic and nutritional quality parameters. From the profiling analysis there was evidence for specific improvements in fruit phytochemical contents; new advanced selections had substantially increased fruit flavonol, anthocyanin, and ellagitannin contents compared to their parent cultivar 'Romina' and, for flavonols and ellagitannins, compared to a standard cultivar 'Elsanta'. Such results confirm that an appropriate breeding program that includes wild strawberry germplasm can produce new strawberry cultivars with a well-defined improvement in fruit nutritional and nutraceutical values.
