Soybean Parentage Information

The soybean parentage information in this database was partially gleaned from the Uniform Soybean Tests for the Southern and Northern regions as well as other sources such as USDA technical bulletins, variety registrations and PVP applications. The strains that appear here were part of the uniform trials and not the preliminary trials. In most cases, the pedigree of individual strains was followed back to named strains in both maternal and paternal lineages where possible. In some cases, the parentage of strains was not specified by the cooperators in the tests. In those cases the maternal and paternal parents are labeled as "Unspecified". In some cases, the actual parental information is partially or completely unknown. In those cases the unknown parentages is labeled with "Unknown". When available, synonyms for the strains were also collected. If a strain was named its PI number was also included as a synonym. In cases where the strain was found to be covered by PVP protection, the PVP registration number was also included. Because of the sources used, not all named soybean strains are listed. For additional information the user should consult the Germplasm Resources Information Network (GRIN) search page.
