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 ...

This paper synthesizes the findings of 22 micro-level studies on technology adoption carried out by the International Maize and Wheat Improvement Center (CIMMYT) with national agricultural research systems in Ethiopia, ...

This paper examines the economics of introducing conservation tillage into existing maize cropping systems in the state of Jalisco, in the western part of Mexico. A stochastic cost-benefit analysis (SCBA) of introducing ...

Drawing on a series of technology adoption studies carried out by the International Maize and Wheat Improvement Center (CIMMYT) in collaboration with national agricultural research systems in Eastern Africa during 1996-98, ...

Interest is increasing worldwide in on-farm conservation as a component of a strategy to conserve crop genetic resources. On-farm conservation may require outside support to small-scale farmers in areas of crop domestication ...

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 ...

This paper describes the current state of international plant breeding research and explains why centralized approach to germplasm improvement, so successful in the past, is being transformed by decentralized local breeding ...

This paper explores social arrangements associated with seed transactions among smallscale maize farmers in the Central Valleys of Oaxaca, Mexico, a centre of crop genetic diversity. A formal seed distribution system has ...

This paper reviews and analyzes economic returns to wheat research in Brazil's main wheat-producing regions in Rio Grande do SuI and Paranci. Between 1975 and 1991, the area planted to wheat in Brazil increased significantly ...

This paper describes and analyzes some of the impacts of wheat improvement research in seven countries in the Eastern and Southern regions of Africa. the countries South Africa, Ethiopia, Sudan, Kenya, Zimbabwe, Tanzania, ...
