Résumé : The objective of these introductory notes is to give a brief overview of the present status of cocoa planting materials and breeding methods. This should help to set the context in which any new technologies would need to be applied and may therefore help in the process of formulating recommendations during this workshop. The opinions expressed here are only meant to be a basis for further consideration; they are the sole responsibility of the author of these notes and neither express the opinion of INGENIC as an association nor that of any sponsoring institution of INGENIC. New technologies used in plant breeding are presently undergoing dramatic development. These technologies can provide new insight into the genetic structure of germplasm and inheritance of selection traits. Thus, they can offer the breeder guidance when deciding on the choice of new parents to be used in breeding and of selection methods. These technologies also have the potential to increase selection efficiency, through marker-assisted selection, and to overcome, through genetic transformation, major production constraints such as losses due to pests and diseases, which are difficult to overcome by traditional methods. Improvement of cocoa planting material involves several steps: germplasm management, characterisation and evaluation, development of breeding tools (early screening methods, biotechnologies), genetic studies, creation and selection of new varieties (variety trials), and multiplication and distribution of new planting materials. The adoption of new technologies in cocoa breeding will depend not only on the efficiency of these methods (accuracy, costs) in relation to alternative methods, but also on the feasibility of introducing these technologies into practical breeding programmes. There is no doubt that the first requirement for integration of any new technologies is the existence of strong traditional breeding programmes.
