Abstract	Phenotypic variation of three ecotypes of Dacryodes edulis (G. Dom) HJ Lam harvested in three agro-ecological zones of the Democratic Republic of Congo was evaluated from January 7 to December 31, 2015. The objective of the study was to determine the phenotypic characteristics of three D. edulis ecotypes from Kongo Central (Kasangulu), Kinshasa (Kimwenza) and Ecuador (Mbandaka), with a view to selecting ecotypes that can be domesticated. The random selection of trees at each site was done at a distance of at least 50 m between trees in order to reduce the probability of crossing between trees. Twenty trees at each site were selected and 25 fruits per tree were harvested (625 fruits per ecotype). The trees in a site are an ecotype. The ripe fruits were harvested following the four cardinal points of the top of each selected tree, stored in the polyethylene nets, tagged and transported within three days to the World Agroforestry Center (ICRAF) Nursery in Kinshasa/Gombe for the characterization. The results obtained showed that there are significant differences between the variables (P <0.001) of the D. edulis ecotypes studied. The weight of the fruit pulp was high among the Kongo central (46.4 g) and Kinshasa (42.7 g) ecotypes. In view of the desired characteristics (thickness and weight of the fruit pulp), the Kinshasa and Central Kongo ecotypes can be used for the domestication of D. edulis.
