Weltzien, E., M. Smith., L. Meitzner, and L. Sperling. 2003. Technical and Institutional Issues in Participatory Plant Breeding from the Perspective of Formal Plant Breeding. A Global Analysis of Issues, Results, and Current Experience. PRGA Program: Cali, Colombia. PPB Monograph No. 1.This paper presents a review of what has been done in participatory plant breeding (PPB) from teh perspective of formal sector institutions such as national plant breeding programs, CGIAR institutes, or extension services. It includes an inventory of PPB cases worldwide, detailed descriptions of about a dozen illustrative cases, analysis of key technical and institutional issues, and assessment of gaps in current knowledge regarding PPB methods, organization and results. For the purposes of this document PPB is defined as approaches that involve close farmer-researcher collaboration to bring about plant genetic improvement within a species.

McGuire S., G. Manicad, and L. Sperling. 2003. Technical and Institutional Issues in Participatory Plant Breeding - Done from a Perspective of Farmer Plant Breeding. PRGA Program: Cali, Colombia. PPB Monograph No. 2.Participatory Plant Breeding (PPB) denotes a range of approaches that involve users more closely in crop development or seed supply. For different perspectives in agriculture and development, which seek to improve crop development, conserve biodiversity or empower farmers, PPB is seen to show much promise. This report considers work which seeks to support farmers' own systems of crop development and seed exchange (farmer-led PPB) in light of these different goals, and of the perspectives of the range of organisations promoting PPB. It presents an overview of farmer-breeding and a framework for support, and gives the first major comparative analysis of farmer-led PPB.
