Abstract
Genetic bottlenecks during domestication and modern breeding limited the genetic diversity of soybean (Glycine max (L.) Merr.). Therefore, expanding and diversifying soybean genetic resources is a major priority for the research community. These resources, consisting of natural and induced genetic variants, are valuable tools for improving soybean and furthering soybean biological knowledge. During the twentieth century, researchers gathered a wealth of genetic variation in the forms of landraces, Glycine soja accessions, Glycine tertiary germplasm, and the U.S. Department of Agriculture (USDA) Type and Isoline Collections. During the twenty-first century, soybean researchers have added several new genetic and genomic resources. These include the reference genome sequence, genotype data for the USDA soybean germplasm collection, next-generation mapping populations, new irradiation and transposon-based mutagenesis populations, and designer nuclease platforms for genome engineering. This paper briefly surveys the publicly accessible soybean genetic resources currently available or in development and provides recommendations for developing such genetic resources in the future. © 2016 by John Wiley & Sons, Inc.
