Farmers' use of improved seed selection practices in Mexican maize : evidence and issues from the Sierra de Santa Marta
The principal advantage of in situ conservation is that it allows adaptive evolutionary processes to continue in the species that are being conserved. For a cultivated crop species, in situ conservation involves farmers' ...
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 diversity and maize seed management in a traditional Mexican community : implications for in situ conservation of maize
Results from a study of maize varieties and seed sources in a traditional community in Mexico raise questions about the relevance of models for in situ conservation of crop genetic resources that are based on geographical ...
Maize technology in Malawi : a green revolution in the making?
This case study of technical change in maize production in Malawi seeks to answer the question of whether the diffusion of improved maize seed and fertilizer among Malawian smallholder farmers will create the sharp yield ...
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 ...
Institutional change and discontinuities in farmers' use of hybrid maize seed and fertilizer in Malawi : findings from the 1996-97 CIMMYT/MoLD Survey
This study records the use of hybrid maize seed and fertilizer by small-scale farmers in Malawi, as well as their opinions about these inputs, from 1989-90 through 1996-97. Its main purpose is to determine whether the ...
Farmers' seed selection practices and maize variety characteristics in a traditionally-based Mexican community
Experimental results and farmers surveys in a Mexican community indicates that farmers' seed selection practices protect the phenological integrity of their maize varieties as they define them, despite numerous factors ...
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 ...
