Interpretive Summary: DNA marker analysis has become a powerful breeding tool with which to improve crops. The USDA-ARS has been involved in pioneering work in this area. The relationship between DNA markers and agronomically important traits was published in a series of papers, providing many practical examples of the use of DNA marker technique. These papers were developed using a series of soybean genotypes known as a soybean mapping population. This population, the NC113 Soybean Mapping Population, was developed by the U.S. Department of Agriculture, Agricultural Research. The population and its genetic marker data are now being released for further study by researchers and to serve as an instructional tool for classroom training of young scientists. The present paper details the release of this population, which is one the first DNA mapping populations to be released in the world.
Technical Abstract: NC113 Soybean Mapping Population was developed by the U.S. Department of Agriculture, Agricultural Research Service (USDA-ARS) and the North Carolina Agricultural Research Service (NCARS). The genetic marker data for NC113 were collected at the Georgia Agricultural Experiment Stations. This population and its genetic marker data have been used extensively to map genes and quantitative trait loci (QTL). It was released to the public in July 2001 by the USDA-ARS and NCARS to facilitate the mapping of additional genes which may segregate in the population and to serve as an instructional tool for training in genetic mapping and QTL discovery. For instructional purposes the phenotypic data for nine traits and DNA marker data for NC113 are freely available to: i) create genetic linkage maps, ii) map "classical" soybean genes conditioning flower color, pod wall color, and resistance to bacterial pustule onto a linkage map, and iii) identify DNA markers associated with QTL for six quantitative traits. Researchers and teachers may also assay the population directly for additional phenotypic traits and apply QTL analysis. Population NC113 was derived from the hybridization of 'Young' and PI 416937. Young is a Maturity Group VI cultivar that was grown widely in the southern USA before 1990. PI 416937 is a Maturity Group VI accession from Japan and is phenotypically distinct from any U.S. cultivar or ancestor.
