| Abstract: | Demand for soybean [Glycine max (L.) Merr.] meal has increased worldwide and soybean importers often offer premiums for soybean containing higher contents of protein and oil. objectives were to detect quantitative trait loci (QTL) associated with soybean seed protein, oil, and seed weight in a soybean mapping population and con rm detected QTL across genetic backgrounds and environments. Two populations of 216 and 156 recombinant inbred lines were developed from Magellan _ pI 438489B and Magellan _ pI 567516C crosses, respectively, and grown in two Missouri environments in 2008. More than 900 simple sequence repeat (SSr) and single nucleotide polymorphism (SNp) markers were used for mapping in each population. Across environments and genetic backgrounds, we have identi ed seven QTL for protein, six for oil, and four for seed weight. Two QTL were detected in common for protein and oil, one on chromosome (Chr.) 5 and another on Chr. 6. Additionally, we have detected one new seed weight QTL on Chr. 6, in the same region of protein and oil QTL. Con rmed protein and oil QTL on Chrs. 5 and 6 may be important targets to nd candidate genes involved in modi cation of protein and oil contents and seed weight using genetic and genomic approaches. Also, SSr and SNp markers closely associated with these QTL can be useful for marker-assisted selection. |
