During the workshop “Modeling Temperature Response in Wheat and Maize,” held from 23 to 25 April 2001 at CIMMYT’s headquarters at El Batan, Mexico, participants examined various approaches for modeling temperature effects ...
Impacts of international research on intertemporal yield stability in wheat and maize: an economic assessment
Critics of modern maize and wheat varieties (MVs) have suggested that, in developing countries, yields of these varieties vary more from season to season than yields of farmers’ traditional varieties, thereby exposing ...
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 ...
Cereal crop productivity in developing countries: past trends and future prospects
This paper synthesizes the evidence on cereal crop poductivity in developing countries over the past 30 years and looks at future prospects for productivity in growth. For more than three decades we have witnessed the ...
Issues regarding targeting and adoption of quality protein maize (QPM)
Improvements in the production characteristics of quality protein maize (QPM) are currently leading to its reintroduction in various areas of the world, both for human and animal consumption. Although the improved QPM ...
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 ...
Maize production environments revisited: A GIS-based approach
This publication presents a GIS-based approach for revising the descriptions of global maize production environments, called "mega-environments" (MEs), used by CIMMYT and its partners. A cluster analysis was performed on ...
