Understanding global trends in the use of wheat diversity and international flows of wheat genetic resources
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 ...
Towards reduced pesticide use for cereal crops in Asia
Several opportunities are available for dramatically reducing the use of agrochemicals in Asia cereal crop production. The first selection of this paper summarizes past trends and future prospects for pesticide use in Asia ...
Farmer plant breeding from a biological perspective: Implications for collaborative plant breeding
Plant breeding by research has become increasingly isolated from the plant breeding of farmers. Collaborative plant breeding (CPB) offers the possibility of bringing these two plant breeding traditions together to increase ...
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 ...
The maize seed industries of Brazil and Mexico: Past performance, current issues and future prospects
This paper describes results of a study of the main factors affecting the development of the maize seed industries in Brazil and Mexico (and, by extension, other developing countries). The authors develop a framework that ...
Linking global and local approaches to agricultural technology development: the role of participatory plant breeding research in the CGIAR
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 ...
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 ...
