Abstract

Fusarium is one of the best-known plant pathogenic fungi, particularly in bananas. This study was conducted to determine the variability of Fusarium isolates and their potential impact on banana quality in Côte d'Ivoire. Apparently healthy bananas were collected from the seven production localities and used to isolate the associated fungi. Morphological characterisation of the fungi included macroscopic (appearance, coloration and mycelial growth) and microscopic (presence or absence of septa, shape, size and conidial concentration) cultural characteristics. The pathogenicity of the isolates was assessed by the absence or presence of rotting symptoms on the bananas. The results showed that the coloration of the Fusarium isolates varied from white to yellow. Some isolates were cottony and thick, while others were flaky and carpeted. The mean macroconidia dimensions were 19.11-29.52 × 2.69-4.64 µm. The average number of septa in macroconidia ranged from 3-5 septa. Macroconidia were fusiform with pointed ends; microconidia were oval with one or two pointed ends. Among the morphometric characteristics of Fusarium isolates, the number and size of macroconidia was the most important discriminating traits for differentiating isolates. In terms of pathogenecity, all isolates caused a symptom except the one isolated in the Dabou area, which did not cause any symptoms. The incubation period varied from 10 to 16 days depending on the isolate.
