Interpretive Summary: Between 1924 and 2011, the National Agricultural Statistics Service reports the average soybean yield in the U.S. has increased an average of 0.34 bushels acre-1 yr-1. Despite many advances in the field and laboratory techniques that should increase the efficiency of soybean breeding and the rate of yield improvement, the average yield increase has changed little over the past nearly nine decades. The narrow genetic base of the soybean crop may be one reason for this lack of change in yield gains. Soybean line LG06-5798 was developed and released by the USDA-Agricultural Research Service and the Illinois Agricultural Experiment Station, Urbana IL. LG06-5798 was derived from the cross of LG00-3372 x LD00-3309. LD00-3309 is a variety released by the Illinois Agricultural Experiment Station and was the highest yielding publicly-developed variety its maturity group for many years. LG00-3372 was released by the USDA-Agricultural Research Service and the Illinois Agricultural Experiment Station and is from the cross of PI 561319A x PI 574477, both introductions from China. In the 2010 USDA Uniform Group IV Test grown at 15 locations, LG06-5798 was the highest yielding entry in the test and was statistically significantly higher yielding than all of the check cultivars including LD00-3309. This demonstrates that the contribution from exotic germplasm can increase the yield of our best soybean varieties. LG06-5798 can be used as a parent in all soybean breeding programs to provide new genetic diversity to improve the yield of U.S. varieties.

Technical Abstract: Soybean [Glycine max (L.) Merr.] germplasm line LG06-5798 was developed and released by the USDA-Agricultural Research Service and the Illinois Agricultural Experiment Station, Urbana IL. LG06-5798 was derived from a single F3 plant from the cross of LG00-3372 x LD00-3309. LD00-3309 was released by the Illinois Agricultural Experiment Station in 2006. LG00-3372 was released in 2005 by the USDA-Agricultural Research Service and the Illinois Agricultural Experiment Station and is from the cross of PI 561319A x PI 574477. LG06-5798 is classified in early maturity group IV. In the 2010 USDA Uniform Group IV Test grown at 15 locations, LG06-5798 was the highest yielding entry in the test and was significantly higher yielding (p = 0.05) than all of the check cultivars including LD00-3309. LG06-5798 is known to be susceptible to races 4 and 7 of Phytophthora sojae. LG06-5798 can be used as a parent for soybean breeding programs to provide new genetic diversity to improve the yield of U.S. cultivars.
