Evaluation and use of the genetic diversity present in the International Cocoa Genebank (ICG,T), in Trinidad

Sounigo O., Christopher Y., Ramdahin S., Umaharan R., Sankar A.. 2001. In : Bekele Frances L. (ed.), End Michelle (ed.), Eskes Albertus (ed.). Proceedings of the International workshop on new technologies and cocoa breeding. Reading : INGENIC, p. 65-71. International Workshop on New Technologies and Cocoa Breeding. 3, 2000-10-16/2000-10-17, Kota Kinabalu (Malaisie).

Genetic diversity is currently assessed in the ICG,T using Isozyme Electrophoresis and RAPID. The information obtained from this assessment is used for establishing a "working collection" within ICG,T containing a reduced number of clones with large genetic diversity and interesting agronomic traits. Proposals are made to integrate the results of this assessment in to the cocoa breeding strategy.
