Abstract

A rare aberrant fruit phenotype was found in cacao (Theobroma cacao L.) in St Augustine, Trinidad. Double fructification instead of single fructification on a single pedicel was observed. The aberration probably occurred as a result of the formation of two pistils in a single flower. Fruits matured as normal, and fruit morphology and seed number were within the range of that reported for normal fruits of the accession observed in Trinidad. The plant is under investigation and the impact of this finding is highlighted.
