Registration of ‘S14‐15138GT’ soybean as a high‐yielding RR1/STS cultivar with broad disease resistance and adaptation

Abstract

S14-15138GT' (Reg. no. 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. 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, frogeye leaf spot, sudden death syndrome, and phomopsis seed decay. In addition to its high yield potential, strong disease resistance package, and broad adaptation, S14-15138GT is a suitable alternative for farmers who want to grow and save seed of glyphosate-tolerant soybean cultivars.

Registration of ‘S16‐3747GT’: A high‐yielding determinate maturity group V soybean cultivar with broad biotic and abiotic stressors tolerance

“…In the face of the growing demand for high‐yielding soybean cultivars in the southern United States, the University of Missouri – Fisher Delta Research, Extension, and Education Center (MU‐FDREEC) soybean breeding program has traditionally developed and released conventional and herbicide‐tolerant cultivars with elevated yielding potential, wide adaptability, unique seed composition, and biotic and abiotic tolerance traits (Chen, Shannon, Ali, et al., 2020; Chen, Shannon, Crisel, et al., 2020; Chen, Shannon, Scaboo, et al., 2020; Chen et al., 2021a, 2021b, 2021c; Shannon et al., 2019). ‘S16‐3747GT’ (Reg.…”

Registration of ‘S15‐10434C’ soybean cultivar with high yield, resistance to multiple diseases, and wide adaptation

“…Through hybridization between carefully chosen diverse parental lines with traits of interest, it is possible to recombine the favorable alleles to develop high‐yielding soybean cultivars with broad disease resistance and adaptability and high seed protein and oil concentration (Shannon et al., 2018). The University of Missouri–Fisher Delta Research Center has a strong traditional breeding program to develop new conventional as well as RR soybean lines with high yield potential and resistance to multiple diseases, desirable seed qualities, and broad adaptation (Chen et al., 2020; Shannon et al., 2019). ‘S15‐10434C’ (Reg.…”

Registration of ‘S16‐5540GT’ soybean cultivar with high yield, resistance to multiple diseases, elevated protein content, and wide adaptation

“…Use of diverse germplasm with desired traits in breeding programs can provide an opportunity to recombine the favorable alleles for high yield and high protein and oil content with resistance to multiple diseases and even wide adaptability (Shannon et al., 2018). The University of Missouri–Fisher Delta Research Center has a strong traditional breeding program to develop new conventional as well as Roundup Ready (RR) soybean lines with high yield potential and resistance to multiple diseases, desirable seed qualities, and broad adaptation (Chen et al., 2020; Shannon et al., 2019). ‘S16‐5540GT’ (Reg.…”
