农民的参与日益被视为开发与农民社区更相关的技术的关键。在植物育种方面，农民的参与被视为增加采用新品种的可能性的关键。本文探讨了参与式植物育种中的选择效率问题，通过测试选择环境和谁在一个种植季节（1997年）对选择系在下一个种植季节（1998年）的表现的影响。选择环境对选择反应的影响比谁做的选择更大，证实了分散选择的重要性。育种家和农民在1997年进行的选择在1998年的许多性状上有所不同，但谷物产量很少。当产量差异显著时，育种家的选择在站点上更有效，而农民的选择在农民的田地里更有效。这项研究的结果表明，有可能组织一个植物育种计划的目标是使作物适应多种物理和社会经济环境：这样的育种计划将，在同一时间，提高生产力和稳定性，增强生物多样性和生产环境友好型品种。
Farmer participation is increasingly seen as a key to develop technologies which are more relevant to farmers' communities. In plant breeding, farmer participation is seen as key to increase the probability of adoption of new varieties. This paper addresses the issue of selection efficiency in participatory plant breeding by testing the effect of selection environment and of who did the selection in one cropping season (1997) on the performance of the selected lines in the following cropping season (1998). Selection environment had a larger effect on response to selection than who did the selection, confirming the importance of decentralized selection. Selections made by the breeder and the farmers in 1997, differed in 1998 for a number of traits, but seldom for grain yield. When the difference for grain yield was significant, breeder's selection was more effective on station, while farmers' selection was more effective in farmers' fields. The results of this study indicate that it is possible to organize a plant breeding program with the objective of adapting crops to a multitude of both physical and socio-economic environments: such a breeding program will, at the same time, increase productivity and stability, enhance biodiversity and produce environmentally friendly cultivars.
