Resumen:
Five of the ten strawberry cultivars (Fragaria x ananassa) currently used in Argentina were characterized and compared by isozyme polymorphisms. The study included three wild species of the Rosaceae family related to Fragaria x ananassa.Fragaria x ananassa) currently used in Argentina were characterized and compared by isozyme polymorphisms. The study included three wild species of the Rosaceae family related to Fragaria x ananassa.Fragaria x ananassa. Isozymes analyzed were phosphoglucoisomerase (PGI), shikimic dehydrogenase (SDH), and leucineaminopeptidase (LAP). Only PGI was useful to identify the Cartuno cultivar and differentiate it from Camarosa, Sweet Charlie, Pájaro, and Enzed Donna cultivars. The correspondence among the band patterns observed in Fragaria chiloensis and all cultivars provides evidence that F. chiloensis is an ancestor to the cultivated strawberries. Band patterns of all Duchesnea species studied were different from those observed in all Fragaria species. Our results constitute further evidence of the taxonomic differences between Duchesnea and Fragaria genera, which were initially considered a single one named Fragaria.Fragaria chiloensis and all cultivars provides evidence that F. chiloensis is an ancestor to the cultivated strawberries.
