Participatory plant breeding: Who did it, who does it and where?

The paper provides an overview of institutions, scientists, and practitioners involved over the years in the various ways in which participatory plant breeding (PPB) is implemented, with indication of the crops involved and the countries in which it took place, or is still taking place. This might help creating a better awareness of the scope (both geographical and crop wise) of the different methodologies as well as of their advantages, disadvantages, applicability, and limitations. Through a literature survey, we found 254 publications showing that over a period of 36 years participatory approaches in plant breeding have been used in 69 countries (10 developed and 59 developing) with 47 crops including self-pollinated, cross-pollinated, and vegetatively propagated crops, by several Institutions including CGIAR centers, universities, and NGOs. We argue that there are no obvious scientific or technical reasons limiting the use of PPB, and we interpret the limited institutionalization as a difficulty to accept the paradigm shift that participation implies.
