‘Sheyenne’ soybean [Glycine max (L.) Merr.] (Reg. No. CV-494, PI 647867) was developed by the North Dakota Agricultural Experiment Station, North Dakota State University, and released on Jan. 28, 2007. Sheyenne has high yield, is tolerant to iron-deficiency chlorosis and resistant to lodging.

Sheyenne is an F₄-derived line, originally designated ND01-3906, with the pedigree Pioneer 9071 X A96-492041. ‘Pioneer 9071’ was developed by Pioneer Hi-Bred Int., Inc. A96-492041 was developed by Iowa State University and never released. The pedigree of A96-492041 is ‘NK S24-92’–‘NK S19-90’. Both NK S24-92 and NK S19-90 were developed by Northrup King Co. Simple Sequence Repeat (SSR) marker data showed that Sheyenne is different from Pioneer 9071 at the following loci: Satt191, Satt373, Satt534, and Satt243. Averaged across 18 testing sites in North Dakota, during the years 2004 through 2006, Sheyenne yielded 260 kg ha^–1 (10%) more than Pioneer 9071 (LSD 0.05 = 12 kg ha^–1) and Sheyenne was four days later in maturity.

The cross leading to Sheyenne was made in the summer of 1998 at Casselton, ND. The F₁ plants were grown in the 1998–1999 Chile winter nursery. The F₂ population was grown in the summer of 1999 and advanced to the F₃ generation by the single-pod bulk method (Fehr, 1991). The F₃ population was grown in the 1999–2000 Chile winter nursery and advanced to the F₄ generation by the single-pod descent method. Individual F₄ plants were grown in the Fargo nursery and threshed in the fall of 2000. F_4:5 plant-rows were evaluated in 2001 at the Fargo, ND nursery. Sheyenne was first tested as ND01-3906 in replicated yield trials in North Dakota in 2002.

Sheyenne was tested in the USDA Uniform Regional Trials: Northern States in 2005 and 2006 (Abney, 2006; Abney, 2005). In two years of USDA Uniform Regional Tests, Sheyenne yielded 343 kg ha^–1 (10%) more than ‘Lambert’ (LSD 0.05 = 16 kg ha^–1) and was one day later in maturity (Orf and Kennedy, 1994). Protein content was 389 g kg^–1 for Sheyenne and 404 g kg^–1 for Lambert. Oil content was 214 g kg^–1 for Sheyenne and 217 g kg^–1 for Lambert. Seed weights of Sheyenne and Lambert are both 0.161 g seed^–1.

Sheyenne was evaluated by the North Dakota State University soybean breeding program for a total of 18 location-years that included 2004 to 2006. Sheyenne yielded 262 kg ha^–1 (10%) more than ‘LaMoure’ and 444 kg ha^–1 (18%) more than ‘Barnes’ in North Dakota trials averaged across the years from 2004 to 2006 (LSD 0.05 = 12 kg ha^–1) (Helms et al., 2005; Helms et al., 2001). Sheyenne matured 25 September, which is two days later than LaMoure and seven days earlier than Barnes. Lodging was rated on a 1 to 5 scale with 1 the best and 5 the worst. Sheyenne had a lodging score of 1.3 compared to LaMoure with a score of 1.2 and Barnes with a score of 1.2, averaged across six locations where lodging was observed. In 2006, extreme lodging was observed under irrigation at Oakes, ND and Sheyenne had a lodging score of 1.8 versus LaMoure with a lodging score of 3.0. Plant height of Sheyenne was 0.78 m compared to LaMoure with a plant height of 0.76 m. Iron-deficiency chlorosis was rated on a 1 to 5 scale with 1 the best and 5 the worst. When Sheyenne was evaluated for iron-deficiency chlorosis in 2004 at four high pH sites in North Dakota, Sheyenne was classified as moderately resistant with scores of 2.6 compared to 2.3 for LaMoure and 3.2 for Barnes (LSD 0.05 = 0.2).

Sheyenne has purple flower color, gray pubescence, brown pod, yellow hila with dull seed coat luster, and indeterminate growth habit. It is a Maturity Group 0 cultivar (relative maturity 0.8) and is generally adapted as a full-season cultivar from 45 to 48° N. lat. Sheyenne was resistant to race 3 of Phytophthora sojae (M.J. Kaufmann and J.W. Gerdemann), the cause of Phytophthora root rot. Breeder seed of Sheyenne will be maintained by North Dakota State University. A small sample of seed for research purposes can be obtained from the corresponding author for at least five years. Protection for Sheyenne under the U.S. Plant Variety Protection Act Title V is pending. Seed of Sheyenne was deposited at the National Center for Genetic Resource Preservation and will be available after the expiration of the U.S. Plant Variety Protection.
