Nearly a century has been spent collecting and preserving genetic diversity in plants. Germplasm banks-living seed collections that serve as repositories of genetic variation-have been established as a source of genes for improving agricultural crops. Genetic linkage maps have made it possible to study the chromosomal locations of genes for improving yield and other complex traits important to agriculture. The tools of genome research may finally unleash the genetic potential of our wild and… 

Exploitation of Natural Biodiversity Through Genomics

The development and application of the advanced-backcross and introgression-line breeding populations for the identification of wild species derived chromosome segments that improve agricultural performance of elite germplasm are reviewed.

It is argued that exotic libraries, which consist of marker-defined genomic regions taken from wild species and introgressed onto the background of elite crop lines, provide plant breeders with an important opportunity to improve the agricultural performance of modern crop varieties.

Molecular population genetics and agronomic alleles in seed banks: searching for a needle in a haystack?

  • D. Prada

  • 2009
This paper reviews some of the theoretical and statistical issues surrounding the use of molecular population genetics tools for the detection of agronomical valuable alleles in seed banks and emphasizes the technical limitations imposed by seed banking that may lessen the success of integrated and multi-disciplinary molecular approaches.

Unlocking wheat genetic resources for the molecular identification of previously undescribed functional alleles at the Pm3 resistance locus

A targeted approach for molecular utilization of gene bank accessions reveals landraces as a rich resource of new functional alleles, and can be implemented for other studies on the molecular diversity of agriculturally important genes, as well as for molecular breeding.

Genomics of plant genetic resources: past, present and future

From the determination of phenotypic traits to the application of NGS to whole genomes, every aspect of genomics will have a great impact not only on PGR conservation, but also on plant breeding programmes.

Leveraging natural diversity: back through the bottleneck.

Genetic Diversity, Conservation, and Utilization of Plant Genetic Resources

This article focuses on the recent development in maintaining the diversity of genetic resources, their conservation, and their sustainable utilization to secure global food security.

Genomic Approaches of Crops Genetic Diversity

For thousands of years, crop genetic diversity (the variation of the genes within a crop species), was the only result of domestication and practices of crop production with relatively few and


Summary Gene flow between crops and their wild relatives is an important process that has strong implications both for conservation of genetic diversity and for plant breeding. Introgression between

Genetics and Breeding

The history of the development of genetic maps in Cynara cardunculus is retraced, starting from the first maps based on a limited number of mostly dominant molecular markers, up to the most recent maps allowing the identification of genomic region influencing key agronomic traits.



Plant genetic resources: a conservation imperative.

This volume reviews the history of crop-plant development, introduction, and conservation in North America, outlines some effective policies and strategies for dynamic genetic conservation in plants, particularly those of direct economic value, and examines a variety of problems in and opportunities for preservation and utilization of the irreplaceable genetic heritage in agriculture and forestry.

DNA-based markers in plants

This chapter discusses molecular marker maps of major crop species, and some concepts and new methods for molecular mapping in plants using PCR-based marker systems and information systems approaches to support discovery in agricultural genomics.

Gene Banks and the World's Food

Gene Banks and the World's Food contributes to the crucial debate on how best to preserve some of society's most valuable raw material. The authors also provide an up-to-date report on the status and

The New Systematics

The New Systematics edited by Julian Huxley, with contributions from twenty-two authors, makes most stimulating reading and is the most amenable to experimental analysis.

Introduction to quantitative genetics

For the next few weeks the course is going to be exploring a field that’s actually older than classical population genetics, although the approach it’ll be taking to it involves the use of population genetic machinery.

Gene Banks and the World's Food

Crops and Man.


At the annual meeting of the Crop Science Society of America in 1975, a week-long symposium entitled “Genetic Vulnerability, Germplasm Resources and Plant Breeding Strategies” reviewed the current status of U.S. grain, forage, and fiber crops, providing a thorough survey of the problem and its potential solutions.
