A Multistate Comparison of Native Octoploid Strawberries from North and South America

ADDITIONAL INDEX WORDS. Fragaria × ananassa, F. virginiana, F. chiloensis, strawberry germplasm resources ABSTRACT. An elite group of 38 strawberry accessions representing all subspecies of the beach strawberry ( Fragaria chiloensis (L.) Miller) and the scarlet strawberry ( F. virginiana Miller) was planted in a replicated design at five locations across the United States, and evaluated for plant vigor, flowering date, runner density, fruit set, fruit appearance, and foliar disease resistance. Considerable genotype × ×× ×× location interaction was observed for many of these traits. However, a few genotypes were impressive at all locations including PI 551735 (FRA 368) with its unusually large, early fruit, and PIs 612486 (NC 95- 19-1), 612493 (Frederick 9), and 612499 (RH 30), which were very vigorous and had unusually good fruit color. Genotypes that were superior at individual locations included PIs 551527 (FRA 110) and 551728 (Pigeon Pt.) in Maryland for their large fruit, and PI 612490 (Scotts Creek) in Oregon which had extremely large fruit, superior color, firmness, and flavor. The PIs 612495 (LH 50-4), 612498 (RH 23), and 612499 (RH 30) performed well as day neutrals at multiple sites.
