This protocol is an application of practice in Allanblackia domestication team as experienced and practiced by the research and development programme in Cameroon, Ghana, Nigeria and Tanzania. It is a research and development tool with particular biases on participatory domestication as basic foundation of quality and quantity seedling development. The preparation of this protocol been developed into modules by its scientific staff in support of various groups participating in domestication of this species. This training manual has been developed for the fol-lowing reasons: • To support the various domestication research and development activities.• To provide reference material for participating institutions and extension agents when they are propagating AB trees.• To provide guidelines and resource material for managers and/or resource persons who wish to organize a training course in the future.In producing this protocol reasonable care has been taken to ensure that all statements represent the best information available.
