| Abstract: | Isolates of Fusarium oxysporum obtained from cucumber worldwide were classified into 3 groups by random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR). All isolates of f. sp. radicis-cucumerinum fall into one group. Isolates of races 1 and 2 of f. sp. cucumerinum fall into a second group related to isolates of f. sp. melonis and niveum. Isolates of race 3 fall into a third group, related to f. sp. momordicae. Because f. sp. radicis-cucumerinum has relatively recently been introduced into Greece, where it is actively spreading and very damaging, RAPD-PCR may be valuable in monitoring populations of F. oxysporum. |
