This project supports the NDSU soybean breeding program core germplasm program. The core germplasm program comprises nearly all of the NDSU soybean germplasm collection including conventional, tofu and natto soybean. The goal is to focus on creating high yielding soybean lines that are stacked with necessary resistances for North Dakota including: soybean cyst nematode, iron deficiency chlorosis, soybean sudden death syndrome, white mold, and brown stem rot. Many of these traits are multigenic and require intense breeding efforts to achieve improvement. Once the superior germplasm is created, it can enter the trait introgression pipeline where acquired herbicide resistances can be added. This proposed project includes every step of creating superior core germplasm from hybridization, early generation advancement, yield testing, pure seed creation, and finally breeder seed increases. My role as the breeder is to oversee and manage the breeding team to assure they are carrying out the breeding pipeline as efficiently, purely, and safely as possible. This includes decision making and hands on field/ seed lab work. This project also allows for hands-on training for interns, undergraduate, graduate students to give them the experience they need to be successful breeders following graduation.
