There are numerous traits that soft white winter (SWW) wheat (Triticum aestivum L.) cultivars require to be successful in the U.S. Pacific Northwest. High yield potential, high grain volume weight, acceptable end‐use quality, winter hardiness, resistance to Cephalosporium stripe, and high falling number are just a few of the desired traits. Although many of these traits are driving factors toward releasing a new cultivar, two traits are essential if a cultivar is to be successful in the Pacific Northwest: stripe rust resistance and strawbreaker foot rot (eyespot) resistance. The objective of this research was to develop a SWW cultivar with improved resistance to current stripe rust races, that carries genes for strawbreaker foot rot resistance, is winter hardy, and has high yield potential in the intermediate (400–500 mm) and high (>500 mm) rainfall regions of eastern Washington. ‘Purl’ (Reg. no. CV‐1166, PI 691558) SWW wheat was developed and released in March 2018 by the Agricultural Research Center of Washington State University. Purl was tested under the experimental designations MAS08019‐92‐1‐S‐s and WA8234, which were assigned through progressive generations of advancement. Purl is a semi‐dwarf cultivar adapted to intermediate‐ to high‐rainfall wheat production regions of Washington. Purl has high‐temperature adult‐plant resistance to stripe rust, carries the Pch1 gene for strawbreaker foot rot, is intermediate in height, has midseason maturity, and has high test weight and grain yield potential. Purl has end‐use quality properties similar to those of ‘Stephens’, ‘Puma’, and ‘Madsen’ and is suitable for cookie, cake, and cracker production.

冬小麦（Stictic aestivum）具有许多特征L.）品种需要在美国西北太平洋地区获得成功。高产潜力，高谷物体积重量，可接受的最终使用质量，耐寒性，对头孢菌条的抗性和高落穗数只是所需的一些性状。尽管其中许多特征是释放新品种的驱动因素，但要使一个品种在西北太平洋地区获得成功，必不可少的两个特征是：抗条纹锈病和抗稻草裂伤性（眼点病）。这项研究的目的是开发一种SWW品种，该品种对当前的条锈病具有更强的抵抗力，该品种携带抗稻草er脚腐烂的基因，耐寒，并且在中间（400-500毫米）和高（ > 500毫米）华盛顿东部的降雨地区。'网址'（注册号CV-1166，PI 691558）SWW小麦由华盛顿州立大学农业研究中心于2018年3月开发和发布。Purl已通过实验代号MAS08019‐92‐1‐S‐s和WA8234进行了测试，这些代号是通过不断进步的代代而分配的。Purl是半矮秆品种，适合华盛顿的中高雨量小麦产区。Purl具有耐高温的成年植物抗条锈病的能力，破草者脚腐病的Pch1基因，中等高度，中期成熟，具有较高的试验重量和谷物产量潜力。Purl具有与“ Stephens”，“ Puma”和“ Madsen”相似的最终使用质量属性，适用于曲奇，蛋糕和饼干的生产。
