Several species of Phytophthora cause cocoa (Theobroma cacao L.) black pod rot on the American continent. A study of ITS (internal Transcribed Spacer) sequences, a region of ribosomal DNA, led to taxonomic separation of the species P. palmivora, P. capsici cacao, P. tropicalis and P. citrophthora cacao. In order to fine-tune this species differentiation study, American strains of Phytophthora present in the CIRAD collection in Montpellier were characterized for their genetic diversity, mating type and certain physiological characteristics.
