Interpretive Summary: LCS ‘Valiant’ (tested as NE10478-1, PI 699380) hard red winter wheat was developed cooperatively by the Nebraska Agricultural Experiment Station and the USDA-ARS, released in March 2020 and then licensed to Limagrain Cereal Seeds (LCS). LCS Valiant was released primarily for its earliness in maturity and superior adaptation to rainfed wheat production throughout Nebraska and the adjacent states. In addition, LCS ‘Valiant’ consistently survived the NE winters, has shown resistance to stem rust, and has good end-use quality. LCS Valiant has excellent grain yield (4244 kg ha-1 or 63 bu/ac) that is superior to other Nebraska wheat varieties. Its grain volume weight was comparable to other high grain volume weight varieties grown in Nebraska. The stature of LCS Valiant (86.7 cm or 34.1” tall, semi-dwarf cultivar) was shorter than other dryland wheat varieties, and it was lodging resistant like many semi-dwarf varieties. LCS Valiant is resistant to leaf rust and moderately resistant to stem rust. It is moderately resistant to moderately susceptible to stripe rust and fungicide applications are recommended whenever this disease is present at economic loss levels. LCS Valiant is moderately resistant to Hessian fly. It is susceptible to wheat stem sawfly, barley yellow dwarf virus, and wheat streak mosaic virus. LCS Valiant is moderately resistant to Fusarium head blight. The end-use quality of LCS Valiant is considered acceptable to good for the milling and baking industries.

Technical Abstract: Historically cultivars developed by the cooperative University of Nebraska-USDA-ARS wheat (Triticum aestivum L.) improvement project tend to be late-maturing and better adapted to the Northern Great Plains. LCS ‘Valiant” (tested as ‘NE10478-1’) was selected for its earliness, agronomic performance, relevant disease resistances, and end-use quality and is adapted to the Central Great Plains. As such, the line was licensed to Limagrain Cereal Seeds for the ability to market outside of Nebraska. LCS Valiant (PI 699380) hard red winter wheat was released in March 2020 by the developing institutions and the licensee. NE10478-1 was a selection in 2011 for uniformity and grain yield from NE10478, which was derived from the cross NI03418/Camelot. The pedigree of NI03418 is W91-248/NE95544 (=McVey 78015/NE88521)//Thunderbird. The final cross of NE10478 was made in 2004. The F1 generation was grown in Yuma, AZ in 2005, and the F2 to F3 generations were advanced using the bulk breeding method at Mead, NE in 2005-2006 to 2006-2007 or sent for Hessian fly resistance screening by the USDA. In 2007-2008, single F3-derived F4 rows were planted for selection. There was no further selection in NE10478 other than to remove off-types thereafter until 2011 when heads were selected to increase uniformity. LCS Valiant was evaluated in replicated trials thereafter. It has excellent winter survival, acceptable disease reactions to many of the common diseases in its target area, and good end-use quality for bread making.
