Vascular Fusarium vascularization caused by the fungus Fusarium oxysporum f.sp. elaeidis, is a major pathological constraint for oil palm cultivation in Côte d'Ivoire where the disease is endemic. Research on integrated pest management was carried out on plots with a high density of Fusarium wilt. Therefore, our study aims to improve plant material in order to minimize the impact of Fusarium wilt on oil palms. We analyzed the evolution of Fusarium disease according to the progenies. The study focused on the observation of the symptoms of Fusarium wilt of oil palms planted from 2002 to 2016 on a cultural history of Fusarium palms. Thus, the percentage of Fusarium wilt expressed and accumulated and the rate of remission of the plants were calculated. Our results revealed that the progenies of the third cycle of recurrent reciprocal selection express high tolerance to Fusarium disease and only four of them showed remission rates. Huge progress has therefore been made on the plant material concerning the tolerance to Fusarium wilt from the 1st to the 3rd cycle.
