Interpretive Summary: Soybean is the world’s largest source of animal protein feed and the second-largest source of vegetable oil for humans, comprising about 90% of US oilseed production. However, diseases can cause significant yield losses every year. High global demand for soybean oil and animal feed and US southern growers’ preference for early maturing cultivars with high-yield potential and resistance to multiple diseases led to the development and release of the ‘S16-5540GT’ soybean cultivar. ’S16-5540GT’ was tested in 88 environments in Missouri and other southern states from 2017 to 2020 for yield and other agronomic traits. ‘S16-5540GT’ has high yield and is resistant to soybean cyst nematode (races 2, 3, and 5), peanut and southern root-knot nematodes, reniform nematode, frogeye leaf spot, Phomopsis seed decay, charcoal rot and moderately tolerant to Cercospora leaf blight and stem canker. ‘S16-5540GT’ is an excellent variety choice for farmers who are interested in glyphosate tolerance for weed control and saving seed for planting.

Technical Abstract: ‘S16-5540GT’ is a mid IV maturity group semi-determinate glyphosate-tolerant high-yielding soybean [Glycine max (L) Merr.] cultivar developed and released in 2020 by the University of Missouri – Fisher Delta Research Center Soybean Breeding Program. High global demand for soybean oil and animal feed and US southern growers’ preference for early maturing cultivars with high-yield potential and glyphosate tolerance led to the development and release of ‘S16-5540GT’ soybean. ’S16-5540GT’ was tested in 88 environments in Missouri and other southern states from 2017 to 2020 for yield and other agronomic traits. On average, ‘S16-5540GT’ yielded 4244 kg ha-1 which was higher than all the tests mean of 3885 kg ha-1. ‘S16-5540GT’ seed averages 411 (41.1%) and 220 (22%) g kg-1 of protein and oil, respectively, on dry seed weight basis. ‘S16-5540GT’ exhibits relative maturity of 4.6 and has white flowers, tawny pubescence and tan pod wall. Seeds are yellow with intermediate luster and black hila and weigh 15.0 g 100-1 seed. ‘S16-5540GT’ plants average 76 cm in height with resistance to lodging. It is resistant to soybean cyst nematode (races 2, 3 & 5), peanut and southern root-knot nematodes, reniform nematode, frogeye leaf spot, Phomopsis seed decay, charcoal rot and moderately tolerant to Cercospora leaf blight and stem canker. This is also chloride excluder. It is an excellent variety choice for farmers who are interested in glyphosate tolerance for weed control and saving seed for planting.
