Farmer plant breeding from a biological perspective: implications for collaborative plant breeding

摘要: Plant breeding by researchers has become increasingly isolated from the plant of farmers. Collaborative (CPB) offers possibility bringing these two traditions together to increase usefulness new crop varieties farmers, especially small-scale farmers working in stress environments with limited external inputs. This paper presents a framework for breeders, social scientists, project personnel, and policy makers understand farmer improving longterm well-being through CPB. Research questions are proposed based on three components basic biological model breeding: genetic variation, environmental variation its interaction genotypes, selection. For each component, authors review range data, conclusions, assumptions research literature about farmers’ 1) knowledge, 2) practice, 3) growing environments. The concludes discussing general implications this approach described understanding perspective can make significant contribution success By posing such as ones suggested paper, more systematic picture breeding, both specific instances general, should emerge. Further testing hypotheses presented here is needed, context CPB projects. could help breeders communicate efficiently other, so that use their knowledge theory, statistical design analysis, access wide diversity, crops techniques managing them effectively. collaboration yield better meet needs conserve diversity situ, thus contributing sustainable agriculture.
