Nested Association Mapping (NAM) of Genes Controlling Soybean Yield and Other Key Traits

Our goal is to improve the yield potential of soybean varieties. To this end we have mapped the chromosomal locations of genes that control yield and other important agronomic traits in both domestic and exotic germplasm using a Nested Association Panel composed of 40 important soybean varieties and cultivars crossed to a common hub parent. Further details about the SoyNAM Project are avaliable. Funding was provided by the North Central Soybean research Program (NCSRP) and the United Soybean Board (USB).

140 Recombinant Inbred Lines (RILs) were developed from each cross between the NAM parents and IA3023.
