Abstract : Fusarium
wilt is the most serious disease of the oil palm (Elaeis guineensis Jacq.) In
Africa. The methods of fighting this disease are mainly based on the search for
tolerant plant material, so the researchers of CNRA were able to make available
to the producers of the genotypes tolerant to the Fusarium wilt. However, two
of these supposedly tolerant genotypes, planted on plot D9-3 in Ehania, a
highly endemic plot, showed symptoms of vascular Fusarium wilt after 9 years of
replanting. The evaluation of production responses in comparison with the
physiological states of other genotypes of the same parental origin showed that
the LM25373 and LM25635 progenies retained their ability to produce in spite of
their doubtful physiological state. The appearance of the external symptoms of
FHB did not affect the cycles of production of these so-called diseased progeny
