| dc.description.abstract | Soybean [Glycine max (L.) Merr.] has historically been subject to extensive breeding efforts aimed at enhancing yield and other agronomic traits. Relatively new to North Dakota, breeding efforts began at North Dakota State University (NDSU) in 1986, where yield gains and genetic diversity were previously not well-characterized. This research investigates yield improvements and genetic diversity within NDSU cultivars. Era trial data analysis of 28 cultivars reveals incremental yield gains amidst considerable variability. Exploration into ancestral pedigree records of 29 released NDSU cultivars identified 49 founders with genetic contributions. Coefficient of parentage estimates revealed only 10 founders collectively contribute over 70% of all NDSU germplasm. Utilizing SNP-based analyses, intricate relationships among cultivars and founders are outlined, offering useful insights for informed breeding strategies. This study underscores the intricate nature of yield advancements and genetic diversity within the NDSU soybean breeding program, accentuating the importance of genetic diversity in plant breeding populations. | en_US |
