TLDR
Large numbers of entries are now lodged in many of the world's germ-plasm collections of crop and pasture plants, and the problems of how best to conserve it and how to use it in plant breeding have intensified.Abstract:
Large numbers of entries are now lodged in many of the world's germ-plasm collections of crop and pasture plants This abundance of material, assembled to guard against its irretrievable loss, has read more

Direct comparison of levels of genetic variation among barley accessions detected by RFLPs, AFLPs, SSRs and RAPDs
Joanne Russell,John Fuller,Malcolm Macaulay,B. G. Hatz,Ahmed Jahoor,Wayne Powell,Robbie Waugh +6 more
TL;DR: RFLPs, AFLPs, RAPDs and SSRs were used to determine the genetic relationships among 18 cultivated barley accessions and the results compared to pedigree relationships where these were available and the choice of appropriate technology for different aspects of germplasm evaluation is discussed.

Genetic diversity and conservation and utilization of plant genetic resources
V. Ramanatha Rao,Toby Hodgkin +1 more
TL;DR: A better understanding of genetic diversity and its distribution is essential for its conservation and use, which will help in determining what to conserve as well as where to conserve, and will improve the understanding of the taxonomy and origin and evolution of plant species of interest.

A mini core subset for capturing diversity and promoting utilization of chickpea genetic resources in crop improvement
Hari D. Upadhyaya,Rodomiro Ortiz +1 more
TL;DR: A two-stage strategy to select a chickpea mini core subset consisting of only about 1% of the entire collection held in trust at ICRISAT’s genebank is suggested, which will prove to be a point of entry to proper exploitation of chickPEa genetic resources.

Back into the Wild – Apply Untapped Genetic Diversity of Wild Relatives for Crop Improvement
TL;DR: This review highlights the significance of crop wild relatives for crop improvement by providing examples of CWRs that have been used to increase biotic and abiotic stress resistance/tolerance and overall yield in various crop species, and discusses the surge of advanced biotechnologies, such as next‐generation sequencing technologies and omics.

The Number of Alleles That Can Be Maintained in a Finite Population
Motoo Kimura,James F. Crow +1 more
TL;DR: This article proposes to examine some of the population consequences of a system of different isoalleles whose frequency in the population is determined by the mutation rate and by random drift, and considers three possibilities: A system of selectively neutral isoallels, a systemof mutually heterotic alleles, and a mixture of heterotic and harmful mutants.
