Abstract:
The Strawberry - The cultivated strawberry Fragaria × ananassa Duch. (2n = 56), is a result of hybridization between two native American species, F. chiloensis (L.) Duch. (2n = 56) and F. virginiana Duch. (2n = 56). Two other species, F. vesca L. (2n = 14), the most widely distributed wild species, and F. moschata Duch. (2n.=.42), are also grown commercially, but on a much smaller scale (Hancock et al., 1992). The meadow strawberry, F. virginiana Duch., is found in Louisiana, Georgia and northward, whereas F. chiloensis (L.) Duch. is of wider distribution and found in North America, Chile, the Andes, the eastern slopes of Argentina, and Hawaii (Scott and Lawrence, 1975). Due to extensive breeding work, it is now possible to grow strawberries in many climates, from the temperate Mediterranean to sub-tropical and taiga zones (Hancock et al., 1992). It was estimated in 1992 that the world production of strawberries was close to two million tonnes (Hancock et. al., 1992), making them commercially the most important soft fruit worldwide (UK value £54m).
