Interpretive Summary: This field guide is to assist with field identification of the original ICS (Imperial College Selection) clones of cacao from Trinidad. The clones have been very important in cacao breeding and widely distributed to many cocoa research institutes around the world. The guide includes photographs of the pods of each accession, phenotypic characterization, and molecular marker data for 13 microsatellite loci. The guide is expected to be useful for cacao breeders and other scientists for field identification of these important clones.

Technical Abstract: This Field Guide to the ICS Clones of Trinidad will be the first of a Series dedicated to concisely presenting all available knowledge on cacao populations or groups of individuals with the potential of producing improved progenies. The information presented in the Field Guide was generated by the efforts of several individuals from the Cocoa Research Unit, The University of the West Indies, Trinidad, and the Beltsville, MD and Miami, FL locations of the USDA-ARS in the USA. The Field Guide presents, in detail, the methods used to image pods, produce SSR fingerprints, pod morphological descriptors and quantitative data. This empowers institutions to produce and print other Field Guides in this Series on cacao populations of their choice. The authors will be happy to advise others wishing to produce other Guides in the Series. For advice on pod morphological descriptors and quantitative data generation Frances Bekele can be reached at fbekele@fans.uwi.tt. For advice on SSR fingerprinting Ray Schnell can be reached at miars@ars-grin.gov. For advice on SSR fingerprinting, pod imaging and photo editing Lizz Johnson can be reached at ljohnson@catie.ac.cr. The second Field Guide in the Series will be produced at CATIE.
