Maize is highly genetically and phenotypically diverse. Tropical maize and teosinte are important genetic resources that harbor unique alleles not found in temperate maize hybrids. To access these resources, breeders must be able to extract favorable unique alleles from tropical maize and teosinte from their population J. B. Holland ( ) · S. Sood Department of Crop Science, North Carolina State...

Genealogical data have been used very widely to construct indices with which to examine the contribution of plant breeding programmes to the maintenance and enhancement of genetic resources. In this paper we use such indices to examine changes in the genetic diversity of the winter wheat crop in England and Wales between 1923 and 1995. We find that, except for one period characterized by the do...

The economic theory of property rights is applied to the issue of the conservation of plant genetic diversity, an issue often discussed in terms of benefit sharing, in order to demonstrate that the assignment of property rights is important for reasons of efficiency as well as for equity. Given the existence of transaction costs within an industry, the location of a property rights assignment i...

Starting in 1926 and continuing for 80+ yr, 11,241 crop genetic materials have been registered as of 31 Dec. 2008. The crop registration process is an important pathway to publically describe and document new and useful genetic materials and to incorporate these into the public domain via the National Plant Germplasm System (NPGS). Crop Registration materials are now searchable via the Germplas...

Access to plant genetic resources is fundamental the development of more resilient and nutritious crops. The efficient effective conservation therefore key ensuring global food security. There are than 1750 genebanks around world, storing various types germplasm including tissue cultures, seeds, embryos pollen. This chapter describes some recent applications science technology improve managemen...
