Objective
Coffee Berry Disease (CBD) due to Colletotrichum kahawae is a major constraint faradic coffee growing in Africa. Crop losses are 20 to 50%. Genetic resistance is the most suitable control method in the African context of smallholders farming. The nature and the transmission of the resistance have to be further investigated through genetic studies based on hybrid trials. Sources of resistance will be looked for in the wild accessions of C. Arabic and some C. canephor. Molecular markers associated with Atlas of resistance will be looked for in inter specific hybrids witch. canephor. Breeding strategies using Marker Assisted Selection will be proposed and developed. This implies to better understand the diversity of the pathogen (aggressiveness, fitness, and molecular markers). In relation with the susceptibility of the varieties, with the environment, and with the typology of the farms a simple model ofther development of the disease will be elaborated and tested. The spraying recommendations will be based on the above findings. The results of these investigations will be combined to propose long-term management strategies taking into account all components of the project.
