EVALUATION OF CANADIAN ACCESSIONS OF FRAGARIA VIRGINIANA MILLER WITH REGARD TO STRAWBERRY BREEDING
Fragaria virginiana Miller and Fragaria chiloensis (L.) Miller are the progenitors of Fragaria × ananassa Duch. Nowadays, innovative strawberry breeding programmes focus on back-crossing strawberry cultivars with their wild relatives. The introgression of accessions of wild species is valuable for cultivar improvement because funnel effects of aroma patterns and resistances are evident in the breeding history of Fragaria × ananassa. In this contribution, Fragaria virginiana seeds from five Canadian sources were sown. The resulting plants were cultivated and taxonomically described as F. virginiana ssp. platypetala, F. virginiana ssp. virginiana and the nothomorph form F. virginiana ssp. glauca × F. virginiana ssp. platypetala. The plants were described regarding growth habit, resistances, flower characteristics including sex, earliness of fruit ripening, fruit shape, size, colour, flavour, yield, Brix value and day neutrality. The selection of individuals resulted in a group of potential breeding partners with promising parameters, in particular, everbearing behaviour. These plants have been added to the Hansabred germplasm collection and they are already being used for breeding new cultivars.
