Indicators of wheat genetic diversity and germplasm use in the people's republic of China
A preliminary study of wheat genetic diversity in the People's Republic of China is presented. Available evidence and basic data related to the ancestry of leading wheat cultivars and the area distribution of dominant ...
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 ...
Farmers' use of improved seed selection practices in Mexican maize: evidence and issues from the Sierra de Santa Marta
The principal advantage of in situ conservation is that it allows adaptive evolutionary processes to continue in the species that are being conserved. For a cultivated crop species, in situ conservation involves farmers' ...
A conceptual framework for valuing on-farm genetic resources
This paper proposes a preliminary conceptual framework designed to support strategic decisions about which crop populations-in a well-defined reference area within a crop's center of diversity-are suitable candidates for ...
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 ...
