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, ...

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 ...

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 ...

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 ...

Through the global analysis and country-level case studies, this report analyzes the efficiency of investments in wheat improvement research at a disaggregated level and explores a range of options for restructuring research ...

Investments over the past 35 years have created s system of national and international research centers that has revolutionized the supply of improved cereal varieties to developing country farmers. The newly created ...

The impacts of maize breeding research for non-temperate environments in the developing world by national agricultural research systems (NARSs) and the International Maize and Wheat Improvement Center (CIMMYT) over 1966-90 ...

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 ...

This publication was prepared in commemoration of CIMMYT's 25th anniversary. It consists of three main sections. The first provides an abbreviated account of the Center's research and related activities. The second summarizes ...
