Nine commercial strawberry cultivars (Fragaria X ananassa Duch.) and 557 clones of wild F. chiloensis (L.) Duch. from the Pacific coast of the United States were tested in the field for resistance to strawberry aphids (Chaetosiphon spp.). No cultivar was highly resistant but ‘Benton’ consistently supported fewer aphids than the other cultivars. In the first evaluation year, 29 clones of F. chiloensis had fewer aphids than the highly resistant ‘Del Norte’ clone of F. chiloensis on 5 sampling dates, although the differences were not statistically significant but in the second year, only 1 clone, RCP-37, had fewer aphids than ‘Del Norte’.
