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 ...
Breeder demand for and utilisation of wheat genetic resources in Australia
As part of an ACIAR-funded project on genetic diversity in wheat in Australia and China, Australian wheat breeders were surveyed to assess the importance of genetic diversity to breeders. This paper reports the findings ...
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 ...
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 ...
Wheat breeders' perspectives on genetic diversity and germplasm use: Findings from an international survey
Wheat breeders working in national wheat research programmes around the world, and particularly those in developing countries, are concerned that in the future scientific advance may be limited because wheat genetic diversity ...
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 ...
