Interpretive Summary: Soybean is one of the most important crops in the United States, producing over 4.4 billion bushels on about 90 million acres in 2018. However, diseases can drastically reduce soybean yield. Incorporation of genetic resistance into high-yielding cultivars represents a sustainable approach to manage diseases and minimize yield losses. Soybean S14-15138GT was evaluated in 83 environments across 11 states and showed high yield potential and wide adaptation in Missouri and other Southern states. It is resistant to soybean cyst nematode races 3 and 14 (HG Type 5. 7 and Type 1. 3. 6. 7), stem canker, frogeye leaf spot, sudden death syndrome, and Phomopsis seed decay. S14-15138GT is a suitable alternative for farmers who want to grow and save seeds of glyphosate-tolerant soybean cultivars.

Technical Abstract: ‘S14-15138GT’ (Reg. No. CV-PI) is a late maturity group IV (RM 4.8) indeterminate high-yielding soybean [Glycine max (L) Merr.] cultivar with glyphosate and sulfonylurea tolerance developed and released in 2017 by the University of Missouri – Fisher Delta Research Center Soybean Breeding program. S14-15138GT is an F4 plant selection from the cross ‘S09—10871’ x ‘S08-9727RRI’. The parent SO8-9727RRI is a breeding line which carries GTS 40-3-2 transgene. S14-15138GT was tested in 83 environments across 11 states and showed high-yielding potential and wide adaptation in Missouri and other Southern states. In the University of Missouri yield trials, S14-15138GT yielded, on average, 110.1% of the tests mean across 19 locations in 4 years (2015-18). Plants of S14-15138GT are 84 cm tall with resistance to lodging and have white flower color, tawny pubescence, and tan pod walls. On average, S14-15138GT seed contain 406 g kg-1 protein and 221 g kg-1 oil on dry seed weight basis. S14-15138GT has a broad disease resistance package including resistance to soybean cyst nematode races 3 and 14 (HG Type 5. 7 and Type 1. 3. 6. 7), stem canker [Diaporthe aspalathi Jansen, Castlebury & Crous formerly named Diaporthe phaseolorum var meridionalis Jansen Castlebury & Crous] (SC), frogeye leaf spot [Cercospora sojina Hara] (FLS), sudden death syndrome [Fusarium virguliforme O’Donell & T. Aoki] (SDS), and Phomopsis seed decay [Phomopsis longicola T. W. Hobbs] (PSD). In addition to its high yield potential, strong disease package and broad adaptation, S14-15138GT is a suitable alternative for farmers who want to grow and save seeds of glyphosate-tolerant soybean cultivars.
