RATIONALE - New coffee hybrids are important for addressing issues of quality, pests & diseases and climate change, but new plant varieties often encounter slow adoption among farmers due to uncertainties and access. Even when coffee hybrids are shown to be more productive and resistant to (a) biotic stresses, less than 5 % of the orchard in Latin America is planted with hybrids each year. A new dissemination strategy is needed, based on access to technology, data and networks, to increase farmer uptake. This is the aim of the H2020 project BREEDCAFS, based on sharing of propagation techniques locally, local assessment of hybrids in agroforestry systems (AFS), and setup of national stakeholder dialog platforms and sustainable agroforestry clusters. Here, we give a first glimpse of the implementation of this new approach. METHODS - For hybrid assessment, on-farm demo-plots with 4 hybrids and a local control were planted in Nicaragua, Costa Rica, Cameroon and Vietnam. Agronomic observations, quality testing, and farmer surveys are carried out to evaluate productivity, profitability and farmer acceptance. Technology for combined somatic embryogenesis (SE) and rooted mini cuttings (RMC) were transferred to partners in Vietnam, Cameroon and Nicaragua, where dialogue platforms have also been created for all stakeholders in the sector. Further, implementation of agroforestry clusters has been initiated with groups of farmers cultivating new hybrids in sustainable AFS, targeted specialty buyers. RESULTS - The combination of SE and RMC is showing to be a lower-cost approach than solely focusing on the complex and expensive method of SE for vegetative propagation of hybrids. The setting-up of rooted mini cuttings nurseries to Vietnam and Cameroon has allowed mass propagation of hybrids locally at reduced costs, while a women's cooperative in Nicaragua now runs a business producing and selling mini-cuttings. Initial field observations are encouraging; in Costa Rica and Nicarag
