As the primary driver of the soybean's [Glycine max (L.) Merr.] economic value, elevated meal protein has become a desired trait in the soybean value chain.Predominantly used in animal feed, the industry has demanded elevated meal protein concentration as a standard to enhance feeding efficiency and reduce costs.Therefore, the University of Missouri-Fisher Delta Research Center soybean breeding program developed and released S09-13185 (Reg. no. GP-449, PI 699628), a non-genetically modified soybean germplasm with elevated soybean protein meal concentration (511 g kg -1 ) and superior agronomic traits. Throughout extensive yield and quality trait trials across over 40 locations in Arkansas, Missouri, Tennessee, and Virginia, S09-13185 demonstrated wide adaptability and yield competitiveness against commercial checks.
INTRODUCTIONSoybean [Glycine max (L.) Merr.] meal (SBM) is the most prevalent source of protein used in animal feed, with an average of 480 g kg −1 of meal concentration. Worldwide, the United States, Brazil, Argentina, and India are the largest exporting countries of SBM, accounting for ∼70% of the world's protein meal consumption (SoyStats, 2020). As the primary driver of the economic value of soybean, nearly all SBM (98%) is consumed by the animal industry, of which 55% is destined to poultry, 25% to swine, 8% to beef, and 7% to dairy (SoyStats, 2019
