The genetic base of soybean breeding programs is relatively narrow. Thus, there is a lack of diversity for many traits for breeders to work with. Two approaches that are used to overcome this barrier are mutagenesis and mining germplasm collections. Mutant populations and natural variation in germplasm collections harbor individuals with phenotypes that extend beyond what exists within breeding programs. With this purpose in mind, we developed a soybean fast neutron mutant population consisting of approximately 27,000 individuals. Previously, we used this population to identify mutants that exhibit seed composition, and shoot and root architecture phenotypes. We plan to continue to genetically...
