Interpretive Summary: Technical Abstract: A history of the various DNA marker types used in the assessment of molecular genetic diversity in soybean [Glycine max (L.) Merr.] is followed by a description of a number of studies on the assessment of genetic diversity. These studies include a review of reports on 1) the quantification and comparison of diversity within and among various groups of cultivated and/or wild soybean genotypes 2) the use of genetic diversity estimates as tools in soybean breeding for increasing useful genetic variation, 3) the measurement of the loss of genetic variation due to domestication or other genetic bottlenecks and 4) the development of unique DNA fingerprints for genotype and cultivar identification. With the imminent availability of the complete soybean genome sequence as a result of the Department of Energy, Joint Genome Institute sequencing effort, the availability of DNA markers for molecular genetic analysis will increase by an order of magnitude. The availability of thousands of DNA markers along with high throughput genetic analysis platforms will rapidly accelerate the analysis of soybean genetic variation and will lead to the analysis of the complete genome of the thousands of soybean types in germplasm collections. The availability of such a dataset will radically alter approaches to soybean genetics and soybean genetic improvement through plant breeding. |
