| Summary, etc. |
This paper analyzes how the role of germplasm development in increasing maize productivity can be greatly enhanced or diminished by social, political, cultural, and environmental considerations. It discusses too the impact of the interdependence of these factors on the recent history of germplasm development, the expectations for the contribution of improved germplasm to higher yields, the components of improved germplasm, the strategies for its improvement, the importance of genetic diversity, and the role of CIMMYT in all these tasks |
