Optimal search in ex situ collections of wheat genetic resources
This paper develops a theoretical model for analyzing gene bank management decisions regarding the search for traits of economic value in ex situ collections of wheat. The model is applied to data on the probability of ...
A conceptual framework for valuing on-farm genetic resources
This paper proposes a preliminary conceptual framework designed to support strategic decisions about which crop populations-in a well-defined reference area within a crop's center of diversity-are suitable candidates for ...
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 ...
The economic impact in developing countries of leaf rust resistance breeding in CIMMYT-related spring bread wheat
This study was undertaken to estimate the economic impact of efforts since 1973 by the International Maize and Wheat Improvement Center (CIMMYT) to develop spring bread wheat varieties resistant to leaf rust caused by ...
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 ...
