‘S13‐1955C’: A high‐yielding conventional soybean with high oil content, multiple disease resistance, and broad adaptation

Abstract

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.

Exploring Machine Learning Algorithms to Unveil Genomic Regions Associated With Resistance to Southern Root-Knot Nematode in Soybeans

“…A total of 717 breeding lines derived from 330 unique bi-parental populations and developed by the University of Missouri – Fisher Delta Research Center (MU-FDRC) soybean breeding program was used in this study. The MU-FDRC soybean breeding program has historically advanced the field of nematode resistance in soybeans and developed and released multiple soybean lines with enhanced levels of SRKN resistance by combining multiple sources of resistance ( Shannon et al, 2019 ; Chen P. et al, 2021 ). The lines comprised 5 years (2017–2021) of internal advanced yield trials at the MU-FDRC.…”

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

“…S16‐3747GT was also evaluated for salt tolerance in the greenhouse of the MU‐FDREEC, where three seeds of each genotype were planted in plastic cone‐tainers using sandy soil as a growth medium with two replications. In this experiment, S05‐11482 (tolerance derived from ‘S‐100’ [PI 548488]) was used as a tolerant check, and ‘S13‐1955C’ (Chen et al., 2021a) was used as a susceptible check. All plants were exposed to 100 mM of salt solution (NaCl) at the V1 growth stage.…”

“…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 ‘S16‐14801C’: A high‐yielding determinate maturity group V soybean cultivar with multiple disease resistance, salt tolerance, and broad adaptation

“…S16‐14801C was evaluated for salt tolerance in a greenhouse at the MU‐FDREEC, where three seeds of each genotype were planted in plastic cone‐tainers using sandy soil as a growth medium with two replications. ‘S05‐11482’ (tolerance derived from ‘S‐100’ [PI 548488]) was used as a tolerant reference check, and ‘S13‐1955’ (Chen et al., 2021a) was used as a susceptible check. All plants were exposed to 100 mM of salt solution (NaCl) at the V1 growth stage.…”

“…Between 1996 and 2016, the cumulative economic losses due to soybean diseases in the southern United States were estimated at $28,896 ha −1 , of which soybean cyst nematode (SCN; Heterodera glycines Ichinohe) was the most suppressive ($4,951 ha −1 ), followed by southern root-knot nematode [SRKN; Meloidogyne incognita (Kofold & White) Chitwood] and other plant-parasitic nematodes accounting for 14% of the economic losses ($4,088 ha −1 ) (Bandara et al, 2020). Because the use of genetic resistance is the most sustainable alternative-economically, environmentally, and socially-to control plant-parasitic nematodes in soybean , the University of Missouri-Fisher Delta Research, Extension, and Education Center (MU-FDREEC) soybean breeding program has devoted tremendous efforts to developing high-yielding soybean cultivars with enhanced genetic resistance to multiple nematodes Chen et al, 2021aChen et al, , 2021cShannon et al, 2019). In addition to biotic stressors, soil salinity represents a major abiotic stressor that limits crop production by inducing ion toxicity and osmotic imbalance in soybean cultivars susceptible to salinity conditions, particularly in irrigated production systems (Bai et al, 2019;Chung et al, 2020).…”
