The Participatory Plant Breeding (PPB) concept emerged twenty years ago, particularly with the aim to build alternative organizations of the plant breeding activities in developing countries. It now as well questions the developed countries, in the frame of a more global expectation to make all the stakeholders more involved in the agricultural production, from the farmers to its final clients. We discuss here some of the questions addressed by this trend with regard to the definition of the ideotype: (a) different forms of PPB? (b) changing the paradigm: Client Oriented Breeding? (c) a new way to manage {genotype * environment} interactions? (d) mainly societal concerns at stake? (e) biodiversity and ideotypes. As the same key, technical, limiting factors are involved in both PPB and classical breeding, it is suggested to consider PPB as one of the ways in the frame of a general expectation for diversification, thus eventually resulting in the promotion of alternative ideotypes, rather than an alternative process.
