Abstract
Gibberella fujikuroi is species complex. This species complex includes Fusarium tabacinum, F moniliforme (= F verticillioides), F. nygamai, F. proliferatum as well as F. subglutinans. Our objective was to develop a technique to differentiate between isolates of F. subglutinans, F. proliferatum and F. verticillioides. Thirty-two strains of F. subglutinans, six strains from F. verticillioides and five strains of F. Proliferatum isolated from maize in Austria were studied using random amplified polymorphic DNA (RAPD). F. subglutinans strains clustered very closely, with similarity ranging from 87~100%. On the other hand, all the amplification patterns of F verticillioides were identical, as well as in the case of F proliferatum. Our results indicated that these Fusaria species are distinct species and hence RAPD markers can be quick and reliable for differentiating them.
