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 ...
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 ...
A regional analysis of maize biological diversity in Southeastern Guanajuato, Mexico
Four environments with contrasting potential for agricultural productivity and infrastructure development were identified in Guanajuato State, Mexico, to test hypotheses about the relationship of maize biological diversity ...
Identifying appropriate germplasm for participatory breeding: an example from the central Valleys of Oaxaca, Mexico
Identifying the appropriate germplasm to be improved is a key component of any participatory breeding effort because of its implications for impacts on social welfare and genetic diversity. This paper describes a method ...
The private and public characteristics of maize land races and the area allocation decisions of farmers in a center of crop diversity
This study uses an approach derived from models of the private and public characteristics of goods to illustrate (1) the overriding importance of variety attributes in farmers' decisions to allocate area among varieties ...
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 ...
The contribution of genetic resources and diversity to wheat productivity: a case from the Punjab of Pakistan
This study makes use of data on wheat production in the Punjab of Pakistan from 1979 to 1985 to 1) examine patterns of varietal diversity in farmers' fields both at the regional and district levels and 2) identify how and ...
Chimanga cha makolo, hybrids, and composites: an analysis of farmers' adoption of maize technology in Malawi, 1989-91
This paper profiles farmers' adoption behavior and varietal choices with respect to local and improved maize technologies (variety, fertilizer application, and other agronomic practices) in three agroeconomic zones of ...
Farmer management of maize diversity in the Central Valleys of Oaxaca, Mexico: CIMMYT INIFAP -- 1998 Baseline Socioeconomic Survey
Descriptive data from the sample survey of households in the study communities enable us to profile the characteristics of: (1) farm households; (2) the maize populations they grow, based on their own descriptors and the ...
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. ...
