Understanding global trends in the use of wheat diversity and international flows of wheat genetic resources
This paper discusses the centers of origin and diversity for bread wheat; sketches historical patterns in the sources and use of wheat genetic resources in modern plant breeding; identifies and compares indicators of genetic ...
Using economics to explain spatial diversity in a wheat crop: examples from Australia and China
Spatial diversity indicators may serve an important function for policymakers as they seek to manage crop genetic diversity and potential externalities associated with diffusion of some types of genetically improved crops. ...
Organization and performance of national maize seed industries: a new institutionalist perspective
This paper proposes a conceptual framework for analyzing the organization and performance of national maize seed industries. The authors begin by reviewing what several leading economic paradigms have to say about the ...
Genetic change in farmer-recycled maize seed: a review of the evidence
This paper summarizes what is known about farm-level maize seed management practices and reviews the theoretical and empirical evidence regarding the relationship between farmers’ seed recycling practices and the genetic ...
Sources of productivity growth in wheat: A review of recent performance and medium-to long-term prospects
Sources of yield growth in wheat are investigated based on a stylized framework of technical change. Evidence suggests that the relative contribution of input intensification to yield growth has diminished in recent years ...
Impacts of international maize breeding research in the developing world, 1966-1990
The impacts of maize breeding research for non-temperate environments in the developing world by national agricultural research systems (NARSs) and the International Maize and Wheat Improvement Center (CIMMYT) over 1966-90 ...
