Résumé : Mislabelling of trees is a common problem for the management of genebanks. A programme was initiated in 1997 in order to evaluate its extent in the International Cocoa Genebank, in Trinidad (ICG,T), using the RAPD technique. The strategy used, the constraints and limitations encountered, and the practical use of the data obtained are described in this presentation. Options for global approaches to identification of cocoa accessions are compared.
