Interpretive Summary: Soybean is one of the major agricultural crops in the United States, producing over 4.4 billion bushels on about 90 million acres a year. However, diseases can cause very significant yield loss every year. Soybean growers are showing continued interest in growing herbicide tolerant cultivars. There has also been an increasing global demand of soybean oil for food, feed and industrial applications. Developing publicly available and broadly adapted cultivars with herbicide tolerance, high yield, disease resistance and high oil content is needed to meet the growers demand and to sustain expected high yield. Soybean S14-9017GT was tested in 122 environments from 2015 to 2018 for yield and other agronomic traits. It is resistant to stem canker, frogeye leaf spot, soybean cyst nematode, reniform nematode, peanut root-knot nematode, sudden death syndrome, and has field tolerance to Phytophthora root rot. In addition to its high yield potential, high seed oil content and broad adaptation across southern states, S14-9017GT is also a suitable alternative for farmers who want to grow and save seeds of glyphosate-tolerant soybean cultivars.

Technical Abstract: ‘S14-9017GT’ (Reg. No. CV-….PI…………) is a maturity group V high-yielding glyphosate tolerant (RR1) soybean [ Glycine max (L) Merr. ] cultivar developed and released in 2017 by the University of Missouri – Fisher Delta Research Center Soybean Breeding program. S14-9017GT was developed by conventional breeding from a cross between ‘LD07-3419’ and ‘S08-9727RR1’. The parent SO8-9727RR1 is a breeding line which carries GTS 40-3-2 transgene discovered by Monsanto Co. The other parent LD07-3419 is a breeding line developed by the University of Illinois soybean breeding program. Before release, S14-9017GT was tested in 122 environments in Missouri and other southern states from 2015 to 2018 for yield and other agronomic traits. On average, S14-9017GT yielded 4314 kg ha-1 which is higher than the all tests mean of 4124 kg ha-1. S14-9017GT seed contains 378 g kg-1 protein and 246 g kg-1 oil on dry seed weight basis. It exhibits relative maturity of 5.3, determinate growth habit, white flowers, light tawny pubescence, and tan pod wall. It has yellow seed with intermediate luster and black hila and seed weight of 14.9 g 100-1. Plants of S14-9017GT are 81 cm tall with resistance to lodging. It is resistant to stem canker, frogeye leaf spot, soybean cyst nematode (races 1, 2, 3, & 5), reniform nematode, peanut root-knot nematode, sudden death syndrome, and has field tolerance to Phytophthora root rot. In addition to its high yield potential, high seed oil content and broad adaptation across southern states, S14-9017GT is also a suitable alternative for farmers who want to grow and save seeds of glyphosate-tolerant soybean cultivars.
