Interpretive Summary: The increasing interest of growers in Southern United States in taller soybean plants for more flexibility during harvest season led to an increased demand for indeterminate late maturity group (MG) IV soybeans. A new soybean cultivar, S14-15146GT, with tolerance to the herbicide glyphosate was developed and released by the University of Missouri – Fisher Delta Research Center Soybean Breeding program with collaboration with USDA pathologists. High global demand for soybean oil, as well as southern growers’ preference for taller soybean plants with early maturity led to the development 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 five important soybean diseases: Phytophthora root rot, stem canker, sudden death syndrome, frogeye leaf spot, and charcoal rot. The early maturity with high-yield potential, high oil content, broad disease resistance package, and wide adaptation make S14-15146GT an excellent choice for southern growers.

Technical Abstract: S14-15146GT is a late maturity group IV (RM 4.6) indeterminate glyphosate-tolerant soybean [Glycine max (L.) Merr.] cultivar (Reg. No. CV., PI ) developed and released by the University of Missouri – Fisher Delta Research Center Soybean Breeding program. High global demand for soybean oil, as well as southern growers’ preference for taller soybean plants with early maturity led the development of this cultivar. S14-15146GT was evaluated in 130 environments across 10 states and showed high-yielding potential and wide adaptation in Missouri and other Southern states. It is resistant to Phytophthora root rot [Phytophthora sojae M. J. Kaufmann & J. W. Gerdemann] (PRR), stem canker [Diaporthe aspalathi Jansen, Castlebury & Crous. formerly named Diaporthe phaseolorum var. meridionalis] (SC), sudden death syndrome [Fusarium virguliforme O’Donell & T. Aoki] (SDS), frogeye leaf spot [Cercospora sojina Hara] (FLS), and charcoal rot [Macrophomina phaseolina Tassi Goid] (CR). S14-15146GT has white flowers, tawny pubescence, and tan pod wall. Seeds of S14-15146GT have black hilum, yellow cotyledon, and intermediate luster. On average, S14-15146 GT seed contains 235.5 g Kg-1 of oil and 390.8 g Kg-1 of protein. The early maturity with RR1 trait, high-yield potential, high oil content, broad disease resistance package, and wide adaptation make S14-15146GT an excellent choice for southern growers.
