Economic criteria for establishing plant breeding programs
A general model of annual costs and lagged annual returns from a plant breeding program is developed to estimate the threshold sizes of a crop industry at which different breeding programs could be economically justified, ...
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 ...
Estimating the economic impact of breeding nonspecific resistance to leaf rust in modern bread wheat
(American Phytopathological Society (APS), 1998)
Breeding for resistance to rust diseases in wheat is an example of productivity maintenance research. Productivity maintenance research is necessary to avoid contractions in the wheat supply curve that result from changes ...

This report presents information on the level of investment in wheat breeding research in developing countries and the impact of that research, and discusses issues related to assessing returns to wheat improvement research ...
CIMMYT 1998-99 World wheat facts and trends: global wheat research in a changing World: challenges and achievements
This report has four parts. The first part focuses on the changing environment in which the international wheat research system functions in developing countries. The authors describe recent trends in developing country ...
1990-91 CIMMYT World wheat facts and trends: wheat and barley production in rainfed marginal environments of the developing world
A synopsis of recent trends in rainfed marginal environments of the developing world is followed by a description of the major wheat and barley farming systems in West Asia-North Africa (WANA) and South Asia (the role of ...
1995/96 World wheat facts and trends: understanding global trends in the use of wheat diversity and international flows of wheat genetic resources
This document describes wheat's origins and the flows of germplasm between various regions of the world. It summarizes some of the tools biological and social scientists use to measure genetic diversity. It examines patterns ...
CIMMYT World wheat facts and trends: supplement 1995 ongoing research at CIMMYT: understanding wheat genetic diversity and international flows of genetic resources
This supplement to the CIMJvfYT World Wheat Facts and Trends series summarizes objectives and preliminary results of a study of wheat genetic diversity and international flows of genetic resources (final results will appear ...
Determining comparative advantage through DRC analysis: guidelines emerging from CIMMYT's experience
Knowledge of comparative advantage is important for developing countries, because potential welfare gains from specialization and trade can be used to foster economic growth. One practical difficulty with using comparative ...
Continuous economic analysis of crop response to fertilizer in on-farm research
This paper proposes a method for building general models based on continuous analysis of data from on-farm research (OFR) in order to derive recommendations for farmers. The data requirements are not excessive for practitioners ...
