Compatibility reaction of 57 trees belonging to 7 Malaysian and 25 Nigerian cocoa accessions is reported. Out of 23 Malaysian trees studied, 12 trees were self-incompatible and 11 self-compatible. Out of the 34 from the Nigerian collection 22 were self incompatible and 12 self-compatible. Both Malaysian and Nigerian collections had similar pattern of distribution for self-compatible and self-incompatible trees. The studies further revealed that though different trees may belong to the same accession, they need not be identical with regard to their compatibility reaction.
