Abstract:

It is difficult for conventional crop breeding system to develop enough suitable cultivars for various environments in organic agriculture or less developed remote regions. Participatory plant breeding （PPB）, oriented by farmer＇s demand and extruded by their leading and participation, can be an important complement of conventional breeding system. PPB could improve the efficiency of new cultivar, breeding utilization and extension, elevate farmer＇s skill and culture quality, and promote the sustainable agriculture development. Through implementing PPB programs organized by CGIAR and other international organizations, hundreds of new crop cultivars were released, and PPB technology system including selection of breeding parents, offspring selection, seed production and distribution etc, was perfecting continuousely. At last, suggestions were put forward for strengthening the PPB research in China.

Key words: participatory plant breeding （PPB）, conventional breeding, new cuhivar, genetic diversity, sustainable agriculture

摘要：

常规育种体系无法满足欠发达边远地区和有机农业等异质环境下多目标的作物新品种需求。参与式植物育种（PPB）针对当地农民需求,突出农民主导和参与,可弥补常规育种体系的不足。PPB可提高新品种选育及推广利用效率、提升农民技能和素质、促进农业可持续发展。通过国际农业研究磋商小组等组织的参与式育种研究计划,已选育数以百计的作物新品种,并不断完善PPB的亲本选配、后代选择、良种生产与推广等技术体系。最后提出了促进我国PPB研究的建议。
