Fruit of the cultivated strawberry ( Fragaria × ananassa Duchesne ex Rozier) are a good source natural antioxidants, which play an important role in protecting human health. Antioxidant levels vary considerably among genotypes. The is hybrid two very different wild progenitor species: F. virginiana Mill. and chiloensis (L.) species valued by breeders as sources novel traits, but have not been evaluated for antioxidant capacity or compounds. objectives this study 1) to evaluate contents activities representatives F . comparison with ), 2) determine compounds most closely correlated these three species, 3) identify genotypes high activity bioactive use cultivar development. 19 accessions from each plus ananassa, , were (oxygen radical absorbance capacity), total phenolics, anthocyanins, ellagic acid, quercetin 3-glucoside 3-glucuronide, kaempferol 3-glucoside, 3-rutinoside, p -coumaryl–glucose, pelargonidin 3-glucoside–succinate, cyanidin 3-glucoside–succinate. 13 tested had significantly higher capacity, anthocyanins than did fruit other will be valuable parent material developing more nutritious cultivars. correlation relative efficiency, lack genotype-by-year interaction suggests that measurement phenolics may better assay later selection stages development program. Of accessions, NC 95-19-1, JP 95-1-1, CFRA 0982, 96-5-3, RH 30 highest should prove useful toward cultivars capacities.
