et al. (2011) employed 23 SSR markers to examine diversity patterns and population substructuring in 57 European cultivars dating from the late 1800s to modern times and 29 others developed outside Europe (mostly North American) from the early 1900s to the present. They observed ‘a progressive abandonment in European breeding efforts of old European cultivars towards mainly North American ones’ and a distinct separation between old European cultivars developed before 1960 and those bred more recently. They found a clustering of cultivars into four groups: (i) mostly old European cultivars; (ii) mixtures of American and modern European cultivars grown across the continent; (iii) mixtures of mostly American cultivars from California and modern cultivars grown in southern Europe; and (iv) an ‘intermediate’ group of cultivars introgressed with F. chiloensis and F. moschata. They warned that the older European material needs to be protected and maintained so that potentially valuable genes from the infancy of strawberry breeding in Europe are not lost.
