Abstract : Soybean (Glycine max L.) is an important crop in the US and worldwide. It has numerous health benefits because of its high contents of protein, oil, isoflavones, and other bioactive compounds. However, it is susceptible to many biotic stresses such fungal, bacterial, and viral diseases and abiotic stresses such as drought and salinity. The objectives of this funded project were to map quantitative trait loci (QTL) for protein, oil, and isoflavones contents in three recombinant inbred line (RIL) populations of soybean. We have achieved 100% of the goals. We have constructed the genetic linkage maps based on the three recombinant inbred line (RIL) populations PI 438489B by Hamilton (PIxH, n=54) (Kassem et al., 2012), Maryland 96-5722 by Spencer (MxS, n=100) (Akond et al., 2013), and Hamilton by Spencer (HxS, n=100) (Akond et al., 2014, under review). We also mapped quantitative trait loci (QTL) for protein, oil, isoflavone contents as well as other important agronomic traits in each of these RIL populations. The results have been disseminated through (1) high quality manuscripts published in well-respected international journals and (2) poster and oral presentations in local, regional, and international conferences. The results are summarized below.
