Soybeans are economically the most important legume grown worldwide. It provides quality protein and oil to food and feed markets in addition to being used for industrial products. The value of soybean could be enhanced by increasing protein, oil, and sucrose contents, while lowering anti-nutritional compounds such as oligosaccharides. Understanding the genetic and environmental factors controlling soybean seed composition is an essential prerequisite for such an endeavor. Three separate studies were initiated to understand the underlying genetics governing soybean seed compositional traits.
