S11-20124C' (Reg. No. CV-532, PI 689118) is a high-yielding semi-determinate early maturity group V (5.1) conventional soybean [Glycine max (L.) Merr.] cultivar developed and released in 2017 by the University of Missouri-Fisher Delta Research Center Soybean Breeding program. It was developed through conventional breeding from a cross between 'S05-11482' × 'S06-4649RR'. The development of high-yielding conventional soybean became advantageous due to premium prices ofered for non-genetically modiied soybean products, as well as lower seed costs compared with herbicidetolerant cultivars. Additionally, early maturity group V (5.1) soybeans are highly desirable for early planting and after wheat (Triticum aestivum L.) in double cropping systems. S11-20124C was evaluated in 113 environments from 2012 to 2016 in Missouri and other southern states. It is demonstrated to be well adapted through its consistent superior or equivalent performance to the commercial checks with similar maturity. S11-20124C has a wide disease resistance package, including moderate resistance to soybean cyst nematode races 1, 2, 3, 5, and 14 (HG Type 2.5.7, Type 1.2.5.7, Type 7, Type 2.5.7, Type 1.3.6.7 respectively) and resistance to southern root-knot nematode and reniform nematode . Seed averages 416 g kg −1 protein and 245 g kg −1 oil. High yield potential, resistance to multiple diseases, and broad adaptation make S11-20124C a good choice for soybean growers across US southern states.

High demand for early‐maturing conventional (non‐genetically modified [GMO]) high‐oil soybean [Glycine max (L.) Merr.] cultivars in the food and special niche markets led to the development and release of ‘S13‐2743C’ (Reg. no. CV‐538, PI 695097). It is a tall, early maturity group IV (relative maturity 4.1) non‐GMO soybean developed and released by the University of Missouri–Fisher Delta Research Center soybean breeding program. This early maturing, indeterminate type cultivar is desired by growers in the southern United States to plant along with later maturity groups to allow flexibility during the harvest season. S13‐2743C has high oil content (238.4 g kg−1) and a broad disease resistance package, including resistance to soybean cyst nematode race 3, phytophthora root rot, stem canker, sudden death syndrome, and frogeye leaf spot. It has white flowers, grey pubescence, and brown pod walls. Seeds have buff hila and intermediate luster. S13‐2743C was tested in 103 environments across eight states and showed high yield potential in Missouri and other southern states, including Arkansas, Kansas, Kentucky, Louisiana, Mississippi, and Tennessee.

The conventional Maturity Group V soybean [Glycine max (L). Merr.] cultivar ‘S13‐1955C’ (Reg. no. CV‐540, PI 695317) was developed and released by the University of Missouri–Fisher Delta Research Center soybean breeding program in 2019. Plants of S13‐1955C have determinate growth habit, white flowers, tawny pubescence, tan pod wall, and seed with black hilum. It has high oil content (227.4 g kg−1) and broad disease resistance including soybean cyst nematode, southern root‐knot nematode, reniform nematode, sudden death syndrome, and frogeye leaf spot. S13‐1955C was tested in 177 environments across 13 states and averaged 101% of the check yield in Missouri and the southern states from 2014 to 2019.

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.

CV-537, PI 693754) is a late maturity group IV (relative maturity 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 F 4 plant selection from the cross 'S09-10871' × 'S08-9727RR1'. S14-15138GT was tested in 83 environments across 11 states and showed high yield potential and wide adaptation in Missouri and other southern states. In the University of Missouri yield trials, S14-15138GT yielded, on average, 110% of the tests mean across 19 locations in 4 yr (2015-2018). Plants of S14-15138GT are 84 cm tall and have white flower color, tawny pubescence, and tan pod walls. On average, S14-15138GT seed contains 406 g kg −1 protein and 221 g kg −1 oil on a dry seed weight basis.

MO 5301D CONV' [ Glycine max (L.) Merr.] (Reg. No. CV-528, PI 688604) is a conventional high-yielding, early maturity group V soybean [Glycine max (L.) Merr.] cultivar developed at the University of Missouri-Fisher Delta Research Center and released by the University of Missouri Agricultural Experimentation Station in 2016. MO 5301D CONV is well adapted to Missouri and other southern states. It was developed by conventional breeding from a cross between a high-yielding line S05-11482 and a F 1 plant of the cross S07-2680 ×LG04-6000. The F 1 plants were grown under lights in the ield, and the breeding population was advanced from F 2 to F 4 generation in Costa Rica using a modiied single-pod descent method. The F 4:5 line was selected and bulk harvested for further agronomic evaluation. Before release, MO 5301D CONV was tested with the designation S12-4718 in 71 environments in Missouri and southern states from 2013 to 2016 for yield and other agronomic traits. MO 5301D CONV yielded higher than the check cultivars in most environments tested. MO 5301D CONV has a relative maturity of 5.3, determinate growth habit, white lower color, light tawny pubescence, and tan pod walls at maturity. The seed has yellow cotyledons with yellow coats and intermediate luster with black hila. MO 5301D CONV performs well across all soil types. It is resistant to stem canker and frogeye leaf spot, is moderately resistant to soybean cyst nematode race 2, peanut root-knot nematode, and sudden death syndrome, and has ield tolerance to Phytophthora root rot. It is also a chloride excluder for tolerance to saline ield conditions. Seed of MO 5301D averages 405 g kg −1 protein and 223 g kg −1 oil. The combination of high yield, resistance to diseases, and broad adaptation makes MO 5301D CONV a good cultivar choice for soybean production across US southern states.
