Présentation de l'éditeur
Cocoa black pod rot causes almost 30 % losses in world
cocoa production. This disease is caused by various species
of the genus Phytophthora. The most harmful species,
P. megakarya, is currently invading Ivory Coast, the leading
producing country. Faced with this threat, teams of researchers
from CIRAD in France, IRAD in Cameroon, CNRA in Ivory Coast
and CRU in Trinidad came together in a research project
on the genetic bases of cocoa tree resistance to Phytophthora
diseases. This research received financial backing from European
chocolate makers through the Caobisco association.This overview presents the results obtained in work undertaken
during the project. Its main purpose is to provide the international
community with knowledge and tools that can be used to breed
cocoa trees with greater resistance to Phytophthora.Improvement of cocoa tree resistance to Phytophthora diseases
covers pathogen diversity, epidemiological knowledge, the genetic
parameters of resistance observed in the field, and practical
breeding aspects. The relevance of different screening tests
involving artificial inoculations and the use of molecular markers
for the selection of resistant material are widely covered.
