Garden strawberry (Fragaria x ananassa) is a hybrid species with a narrowed allelic diversity due to intensive breeding. We studied the chemical composition and sensory properties of 13 progenies (reconstructed garden strawberry from diverse F. chiloensis and F. virginiana germplasms) and compared to cultivars 'Honeoye', 'Korona' and 'Polka'. Polar metabolite profiles (1H NMR) were associated with ripeness and origin of the wild parent. Volatile compounds not commonly present in commercial cultivars were observed, and the total content of volatiles and specifically esters were present in higher concentrations in the hybrids (HS-SPME-GC-MS). Descriptive sensory analysis indicated the hybrids were less red, and the anthocyanin contents (UHPLC-DAD), especially pelargonidin glycosides, were lower in the hybrid strawberries. Hybrids were also smaller, and had higher overall odour and overall flavour intensities. Hence, the reconstruction from wild sources enabled the introduction of new chemical, colour and flavour properties of high interest into the garden strawberry.
