Interpretive Summary:

Technical Abstract: Soybean has been grown in the United States for more than fifty years, with the value of the crop primarily residing in seed protein meal and seed oil. Work over several decades has resulted in an unprecedented number of genetic markers for a crop plant and an extensive and rigorous consensus genetic map. The development of the genetic map has directly enabled and accelerated the use of quantitative trait loci (QTL) methodologies to ascertain the specific regions of the genome responsible for various seed-quality traits. As such, many researchers and breeders have focused their efforts on understanding the genetic architecture that underlies these traits, through hybridization of cultivars with contrasting phenotypes and subsequent genetic marker analysis of progeny. This strategy has led to a staggering number of QTL studies for soybean seed traits over the last few decades. Though the seed traits that have been investigated appear quite diverse, the ultimate goal of all such studies is to uncover the genetic architecture of seed development, and discern gene variants that are associated with improved seed value and utility. In this review chapter for the forthcoming 2011 monograph “Designing soybeans for 21st century markets”, we detail recent scientific developments in the identification of gene alleles responsible for “value-added” soybean seed traits and the application of this knowledge to improve soybean breeding efforts.
