S14‐15146GT (Reg. no. CV‐534, PI 691841) is a late‐maturity group IV (relative maturity 4.6) indeterminate glyphosate‐tolerant soybean [Glycine max (L.) Merr.] cultivar developed and released by the University of Missouri Fisher Delta Research Center Soybean Breeding program. High global demand for soybean oil and US southern growers’ preference for taller soybean plants with early maturity led to the release of this cultivar. S14‐15146GT was evaluated in 130 environments across 10 states and showed high yield potential and wide adaptation in Missouri and other southern states. It is resistant to Phytophthora root rot, stem canker, sudden death syndrome, frogeye leaf spot, and charcoal rot. S14‐15146GT has white flowers, tawny pubescence, and tan pod walls. Seeds of S14‐15146GT have black hilum, yellow cotyledon, and intermediate luster. S14‐15146 GT seed averages 235.5 and 390.8 g kg⁻¹ oil and protein content, respectively. The early maturity with the first‐generation Roundup Ready trait, high yield potential, high oil content, broad disease resistance package, and wide adaptation make S14‐15146GT an excellent choice for southern growers.
