Comparative virulence of Hawaiian Fusarium oxysporum isolates on Acacia koa seedlings
Sixty-one fungal isolates within the Fusarium oxysporum species complex isolated from Acacia koa plants or rhizosphere soil in Hawaii were tested for pathogenicity on young koa seedlings. Only about 15% of these were considered highly- or moderately-virulent in greenhouse inoculation tests. On the other hand, more than 50% of the tested isolates either exhibited low virulence or were considered nonpathogenic. Highly-virulent isolates were easily identified because they killed nearly all inoculated seedlings during the 90-day tests. Non-pathogenic isolates often did not cause disease symptoms on any of the 24 seedlings exposed per isolate. We have confidence that our testing procedure can be used to easily and consistently identify highly-virulent and non-pathogenic isolates within Hawaiian populations of F. oxysporum and may be used to screen koa families for potential disease reistance.
