'''Fragaria × vescana''' is a [[hybrid]] [[strawberry]] [[cultivar]] that was created in an effort to combine the best traits of the [[Garden Strawberry]] (''Fragaria x ananassa''), which has large berries and vigorous plants, with the [[Woodland Strawberry]] (''Fragaria vesca''), which has an exquisite flavour, but small berries.
This cross cannot take place naturally. ''Fragaria x ananassa'' has eight sets of [[chromosomes]] whereas ''Fragaria vesca'' has only two sets. Repeated attempts to cross these resulted in [[infertility|sterile]] offspring.
Researchers treated tissue from a ''Fragaria vesca'' plant with [[colchicine]] to create a [[mutant]] plant with four sets of chromosomes. This mutant was then crossed with a ''Fragaria x ananassa'' plant, and vigorous fertile offspring were obtained. The offspring were found to be [[polyploidy|decaploid]], (having ten sets of chromosomes).
''Fragaria × vescana'' is not yet commercially important, but remains under development. While the plants are vigorous like their ''F. × ananassa'' parents, and the berries have the excellent flavour of the ''F. vesca'' parents, the berries are still quite small.
==''F. x vescana'' cultivars==
The following decaploid strawberries were released by the Swedish breeding program at Balsgård:
'''Annelie''' (1977)
'''Sara''' (1988) — Annelie x [(Sparkle x ''F. vesca'' 4x) open pollinated]
'''Rebecka''' (1998) — (Fern x ''F. vesca'' 4x) x ''F. x ananassa'' F861502
German ''F. x vescana'' cultivars:
'''Spadeka''' (1990?)
'''Florika''' (1990) — (Sparkle x ''F. vesca semperflorens'') x Klettererdebeere H.
