Résumé : Different DNA marker types were used to construct linkage maps in coconut (Cocos nucifera L.; 2n = 32). In this study, we present a reference map in a mapping population from con-trolled cross involving the genotype EAT0707 representing an East African Tall ecotype. More-over, five other satellite maps involving different "Tall" and "Dwarf" coconut ecotypes such as EAT 1011, RLT0710, LAGT07, MYD20, RIT(PO2664) are also available. The EAT0707 map contains actually a total of 707 markers and has a length of 2083 cM. The 16 linkage groups corresponding to the 16 chromosomes have between 22 and 77 markers each and vary between 99 and 130 cM in length. The other five linkage maps (except RLT0710), are composed of 16 linkage groups and contain between 39 and 253 markers. The lengths of these maps vary between 243 and 2478 cM. Furthermore, several QTL related to growth and other characters of interest have been identified in the different populations.
