Abstract: | Almost 500 clones of wild cocoa trees (Theobroma cacao L.) grown from pods collected in 1987 from wild mother-trees in the Camopi and Tanpok river basins (southeastern French Guiana) have been distributed in around fifteen cocoa producing countries since 1988. The name of those clones always bears the GU prefix (for “Guyane”, i.e. French Guiana). All the germplasm of the same geographical origin present in the CIRAD collection at Paracou-Combi (Sinnamary, French Guiana), i.e. more than 1600 trees, has been abundantly studied for its morphological characterization, its agronomic assessment or its genetic diversity. Other assessment work, primarily on resistance to certain diseases, has been carried out by CIRAD in Montpellier, or in various countries by other organizations. |
