The soybean [Glycine max (L.) Merr] cultivar ‘S11‐17025C’ (Reg. no. CV‐558, PI 701486) was developed and released by the University of Missouri‐Fisher Delta Research, Extension, and Education Center (MU‐FDREEC). S11‐17025C is a conventional, early maturity group V (relative maturity, 5.2) with high yield potential with a determinate growth habit. It is a chloride excluder for tolerance to high‐chloride field conditions. It has broad disease resistance, including soybean cyst nematode races 1 (HG type 2.5.7), 2 (HG type 1.2.5.7), 3 (HG type 5.7), and 5 (HG type 2.5.7); southern root‐knot nematode; reniform nematode; and sudden death syndrome. S11‐17025C was tested in 133 environments across 10 states, including Alabama, Arkansas, Illinois, Kansas, Louisiana, Missouri, Mississippi, North Carolina, Tennessee, and Virginia, in 2012–2016. It was evaluated in yield tests at the MU‐FDREEC (2012–2016), USDA Uniform Soybean tests (2013–2016), and soybean state variety tests (2015 and 2016). S11‐17025C yielded 104% of the commercial check mean across multiple environments. 17025C has broad adaptation across the Mid‐south where growers may benefit from premium prices offered for conventional soybeans. S11‐17025C can also serve as germplasm for use in crosses in breeding programs.
