Abstract: | 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.
