Abstract:
The genus Fragaria has a basic chromosome number of seven (x=7) (Ichijima, 1926), and four main fertility groups are recognized: the diploids (2n=2x=14) which include the model species for the genus, F. vesca, (Oosumi et al., 2006) amongst the 14 described species; the tetraploids (2n=4x=28) including F. orientalis; the single hexaploid species F. moschata (2n=6x=42); and four octoploid species (2n=8x=56): F. chiloensis, F. iturupensis, F. virginiana and the hybrid cultivated strawberry, F. ×ananassa.
