Interpretive Summary: The development of soft white winter (SWW) wheat varieties requires numerous traits to be successfully commercialized in the low to intermediate rainfall (<400 mm average annual precipitation) wheat production regions of Washington State. Winter hardiness, high grain volume weight, acceptable end-use quality, and resistance to stripe rust, Fusarium crown rot (FCR), strawbreaker foot rot, and snow mold. Two essential traits for the low to intermediate rainfall production regions of Washington State are emergence from deep planting and high grain yield under low annual rainfall conditions. The objective of this research was to develop a SWW variety for production in regions with <400 mm annual precipitation, with the ability to emerge from deep planting, is winter hardy, has improved resistance to important diseases of the region, has acceptable end-use quality for export markets, and has high grain yield potential. ‘Devote’ SWW wheat was developed and released in March 2019 by the Agricultural Research Center of Washington State University. Devote is a semi-dwarf variety adapted for the low to intermediate rainfall wheat production regions of Washington State. Devote emerges well under deep planting conditions, is winter hardy, has high-temperature, adult-plant resistance to the current races of the stripe rust pathogen, carries the Pch1 gene for strawbreaker foot rot, is resistant to FCR and tolerant to snow molds, is intermediate in height, has late-season maturity, and has high grain volume weight and grain yield potential. The end-use quality properties of Devote are similar to those of ‘Stephens’, ‘Otto’, and ‘Puma’ and are acceptable for cookie, cake, and cracker production.

Technical Abstract: The development of soft white winter (SWW) wheat (Triticum aestivum L.) cultivars requires numerous traits to be successfully commercialized in the low to intermediate rainfall (<400 mm average annual precipitation) wheat production regions of Washington State. Winter hardiness, high grain volume weight, acceptable end-use quality, and resistance to stripe rust (caused by Puccinia striiformis Westend. f. sp. tritici Erikss.), Fusarium crown rot (FCR) (Fusarium culmorum (Wm.G. Sm.) Sacc. and F. pseudograminearum O’Donnell & Aoki), strawbreaker foot rot (Oculimacula yallundae Crous & W. Gams and O. acuformis Crous & W. Gams) and snow mold (Microdochium [Fusarium] nivale, Typhula idahoensis, T. ishikariensis, and T. incarnata). Two essential traits for the low to intermediate rainfall production regions of Washington State are emergence from deep planting and high grain yield under low annual rainfall conditions. The objective of this research was to develop a SWW cultivar for production in regions with <400 mm annual precipitation, with the ability to emerge from deep planting, is winter hardy, has improved resistance to important diseases of the region, has acceptable end-use quality for export markets, and has high grain yield potential. ‘Devote’ (Reg. No. CV-xxxx, PI xxxxxx) SWW wheat was developed and released in March 2019 by the Agricultural Research Center of Washington State University. Devote was tested under the experimental designations SWW10035-DH-8 and WA8271, which were assigned through progressive generations of advancement. Devote is a semi-dwarf cultivar adapted for the low to intermediate rainfall wheat production regions of Washington State. Devote emerges well under deep planting conditions, is winter hardy, has high-temperature, adult-plant resistance to the current races of the stripe rust pathogen, carries the Pch1 gene for strawbreaker foot rot, is resistant to FCR and tolerant to snow molds, is intermediate in height, has late-season maturity, and has high grain volume weight and grain yield potential. The end-use quality properties of Devote are similar to those of ‘Stephens’, ‘Otto’, and ‘Puma’ and are acceptable for cookie, cake, and cracker production.
