“…In addition to K73-18, key sources of late ripening from diverse genetic backgrounds were 'Pandora' and 'Bogota' (ASHS Press, 1997). Key sources of fruit firmness were 'Scotland', 'Allstar', and 'ArKing' (Dale et al, 1993;Galletta et al, 1981;Moore, 1982). The genetic background of 'Valley Sunset' is geographically diverse, making it difficult to place it in one of the specific cultivar groups proposed by Sjulin and Dale (1987).…”

Additional index words. Fragaria •ananassa, fruit breeding, cultivar, late season 'Valley Sunset', a short-day strawberry (Fragaria •ananassa Duchesne ex Rozier), was commercially introduced in Canada in May 2009 by the Atlantic Food and Horticulture Research Center of Agriculture and Agri-Food Canada (AAFC). 'Valley Sunset' produces medium yields of very large, sweet-tasting fruit ripening in the late season offering growers a cultivar to extend the harvest season beyond that of 'Cabot' and 'Bounty'. Origin 'Valley Sunset' is a seedling of a K94-15 • K95-24 cross made under the direction of A.R. Jamieson in 1998 at Kentville, N.S. (Fig. 1). It is the first introduction from a program of crosses begun in 1989 designed to extend the harvest season beyond 'Bounty' (Craig and Aalders, 1972) with improvements in fruit size and firmness. During the mid-1980s, we considered introducing K73-18, a secondgeneration derivative of 'Vesper' (Fig. 1), but despite high yields of large fruit in the

BACKGROUND: The fungal disease verticillium wilt has been recognized as an obstacle to strawberry production since its initial description in 1931. The full potential of genetic resistance as a solution to this problem has yet to be determined or realized. OBJECTIVE: Our investigations are concerned with defining new sources of resistance to verticillium wilt disease in cultivated and wild strawberry germplasm, and with advancing genetic studies on the basis of resistance/susceptibility. METHODS: We screened 23 diploid, 1 decaploid, and 26 octoploid Fragaria (strawberry) germplasm accessions and cultigens for response to root-dip inoculation with Verticillium dahliae isolate V1. Pedigree relationships of 10 studied cultigens were examined. Crosses were performed between resistant and susceptible accessions. RESULTS: Variability in inoculation response existed within and between species at diploid and octoploid levels. Very or moderately resistant accessions were found within each of three diploid and three octoploid species. Moderately or very susceptible accessions were documented within F. vesca and each octoploid species. Segregation for resistance/susceptibility was evident in progeny populations. CONCLUSIONS: The verticillium wilt resistance ratings reported here and discussed in relation to prior studies adds to the body of publically available knowledge about sources of wilt resistance and susceptibility in Fragaria germplasm.
