Integration of genetic, genomic and marker-assisted selection approaches to build durable resistance to Phytophthora in new cocoa varieties


This project has provided numerous molecular resources, publically available, and original results which have openned new fields of research, and which will continue to be valorised. We can mention particularly : the candidate gene validation, the deciphering of metabolic pathways involved in the phytophthora resistance mechanism using gene network approaches, and the marker assisted selection based on a high marker density, along all the genome, to predict and improve more efficiently the resistance level of new cocoa varieties.
