Exotic soybean germplasm can be used to increase novel genetic diversity and yield potential of cultivars.

Modern North American soybean (Glycine max [L.] Merr.) cultivars have been derived from only a few ancestors. The objectives of this research were to develop breeding lines with novel genetic diversity that were equivalent to the yield of a commercial cultivar parent and within those lines identify regions of novel genetic diversity that were not present in the Corteva Agriscience elite soybean germplasm pool. Nine lines created from diverse germplasm (USDA-ARS breeding program at the University of Illinois) were crossed to a RM34Elite parent to develop populations and sublines for yield testing. Across yield tests at 30 locations conducted between 2014 and 2016, eleven breeding lines were identified that were equivalent …
