Characterisation of several isolates of Fusarium oxysporum f. sp. elaeidis for the selection of fusarium-resistant oil palm varieties

This work was aim to evaluate the pathogenicity and level of aggressiveness ten strains Fusarium oxysporum f. sp. elaeidis (Foe) on palm oil seedlings susceptible vascular wilt. For this purpose, radial growth, sporulation morphological characteristics Foe from farm Cameroon Development Corporation (South-west) were studied in vitro. In addition, 500 wilt aged 5 months distributed a randomized complete block device, inoculated with said strains. External symptoms observed those correlation between these parameters also investigated. The data collected prenursery did not establish significant difference isolates. However, regarding pathogenicity, 7 have shown high pathogenicity. As for strain F presented fastest growth 8.12 cm diameter, unlike strainI whose lowest is 3.98 diameter. C one that abundantly sporulated126,5x105spores/ml; however, isolates B J do sporulate. No detected different parameters. But, considering results obtained, I could be most aggressive can potentially used test timber yard specialized Centre research La DIBAMBA select resistant
