‘Steele-ND’ (Reg. no. CV-965, PI 634981) is a hard red spring wheat (Triticum aestivum L.) cultivar developed at North Dakota State University (NDSU) and released by the North Dakota Agricultural Experiment Station (NDAES) in January 2004. Steele-ND was released because it combines a good level of Fusarium head blight (FHB) {caused by Fusarium graminearum Schwabe [telomorph Gibberella zeae (Schwein.) Petch]} resistance, high grain yield, and high end-use quality for the domestic and export wheat markets.
Steele-ND is an awned cultivar with middense, inclined, and tapering spikes. The culms are white and the peduncle is slightly recurved. The awns are white and 8 to 10 cm in length. The glumes are white, medium, elevated, acuminate; and the shoulder and beak are medium width. The kernels are rounded, hard, red, and oval; the germ is midsized; and the brush is medium.
Steele-ND was selected from the cross ‘Parshall’ (PI 613587)/5/‘Grandin’ (PI 531005)/3/IAS20*4/H567.71//‘Amidon’ (PI 527682)/4/Grandin*2/‘Glupro’ (PI 592759) that was made in 1996. Grandin, Amidon, Glupro, and Parshall are hard red spring wheat (HRSW) cultivars developed by NDSU and released by NDAES in 1988, 1989, 1995, and 1999, respectively. IAS20*4/H567.71 is a breeding line introduced from the International Wheat and Maize Improvement Center (CIMMYT), Mexico; for its high resistance to leaf rust (caused by Puccinia triticina Eriks.). The F1 was grown in the greenhouse and F2 grown in the field at Casselton, ND, in spring and summer of 1997. Two hundred spikes were selected from F2 and advanced to F3 in the greenhouse in fall of 1997 using single seed descent. Selection of spikes in the F2 generation was based on agronomic appearance and reactions to FHB and foliar diseases. One spike from each F3 plant was selected, harvested, threshed, and planted in a F3:4 plot in 1998 at Casselton. The selected F3:4 plot of Steele-ND was harvested, threshed in bulk, and included in the Preliminary Yield Trial (PYT) as an F3:5 at two locations (Prosper and Casselton, ND) in 1999. Ten F3:5 selected spikes from the Casselton PYT were harvested, threshed in bulk, and sent to Christchurch, New Zealand (NZ), in 1999–2000 for seed increase and generation advancement (F3:6) in a four-row 5-m-long plot. F3:7 seed from the NZ increase was used to establish the Advanced Yield Trial in ND in 2000. Subsequently, the line was tested as ND 741 (F3:8) in the ND Variety Trials (NDVT) from 2001 to 2003. Steele-ND was also tested in the HRSW Uniform Regional Nursery (URN) and Uniform Regional Scab Nursery (URSN) from 2001 to 2003 in North Dakota, Minnesota, South Dakota, Nebraska, Montana, Wyoming, Washington, and Manitoba, Canada. The first seed purification of Steele-ND was in 2001 at Prosper, ND, when tall, early, and awnless variants were rouged before harvest. Further seed purifications of Steele-ND were done in the F3:9 and F3:10 generations by discarding variants from the seed increase fields before harvest.
