合作植物育种是一种作物改良方法，包括密切关注农民与正式植物育种者之间的具体适应和相互作用，以更好地满足这些农民的需求。能够充分利用农民和育种者的知识和技能的合作互动将取决于对各自相关知识和技能的理解。为了促进这种与使农民选择实践更有效的目标的相互作用，本文所述的工作试图提高外部研究人员对农民对其人口、生长环境和对选择反应的期望的基本看法的理解。在墨西哥瓦哈卡州中央山谷的两个社区的玉米农民中，采用了各种方法来实现这一目标。农民对玉米品种类型库的决定意味着基于当地遗传和环境变化的评估。在高遗传力和低遗传力性状之间以及对选择的预期反应之间做出了明确的区分，然而，农民感兴趣的一些性状，如大种子大小，可能涉及到其在后代中表达潜力以外的考虑。
Collaborative plant breeding is an approach to crop improvement that includes close attention to specific adaptation and interaction between farmers and formal plant breeders to better meet the needs of those farmers. Collegial interaction capable of making best use of the knowledge and skills of farmers and breeders will depend upon an understanding of those in terms that are relevant to each. To facilitate this interaction with the goal of making farmer selection practices more effective, the work described here sought to improve outside researchers' understanding of farmers' fundamental perceptions about their populations, growing environments, and expectations for response to selection. Various methods were used to accomplish this with a small sample of maize farmers in two communities in the Central Valleys of Oaxaca, Mexico. Farmers' decisions about maize varietal type repertoires imply assessments based on genetic and environmental variation in the local context. A clear distinction was made between traits of high and low heritability and expected response to selection, however, some traits of interest to farmers such as large seed size may involve considerations other than their potential for expression in the progeny generation.
