Soft white winter (SWW) wheat (Triticum aestivum L.) cultivars with the Clearfield Production System technology are an important tool for producers in wheat production regions of Washington State. Paired with the use of the group 2 (Amino Acid Inhibitors/ALS) Beyond (BASF Corporation) herbicide (imazamox), tolerant wheat allows producers options where the current herbicide chemistry has not been adequate to control grass weeds. The objective of this research was to develop a two‐gene Beyond‐tolerant SWW wheat cultivar with improved resistance to the stripe rust pathogen and strawbreaker foot rot, maintains high yield potential across production regions, and has improved end‐use quality. ‘Stingray CL+’ (Reg. no. CV‐1171, PI 691557) SWW wheat was developed and released in March 2019 by the Agricultural Research Center of Washington State University. Stingray CL+ was tested under the experimental designations MAS100095‐2‐1‐S10‐1 and WA8275 CL+, assigned through progressive generations of advancement. Stingray CL+ is a two‐gene Beyond‐tolerant semi‐dwarf cultivar adapted for the high rainfall wheat production regions of Washington. Stingray CL+ has high‐temperature adult‐plant resistance to the stripe rust pathogen, is heterogeneous for the Pch1 gene for strawbreaker foot rot, is tolerant to the chemistry of Beyond herbicide, is intermediate in height, has midseason maturity, and has high grain volume weight and grain yield. The end‐use quality properties of Stingray CL+ are acceptable to meet both domestic and export market standards.

注册“ Stingray CL +”软白冬小麦

柔软的白色冬季（SWW）小麦（Triticum aestivum具有Clearfield生产系统技术的L.）品种是华盛顿州小麦产区的生产者的重要工具。配合使用超越第2组（氨基酸抑制剂/ ALS）（BASF Corporation）除草剂（依玛沙莫），耐受性小麦为生产者提供了在当前除草剂化学物质不足以控制草杂草的情况下的选择。这项研究的目的是开发两基因超耐受的SWW小麦品种，该品种对条锈病病原体和稻草破碎者的脚腐病具有更强的抵抗力，在整个生产区域保持高产潜力，并改善了最终使用质量。华盛顿州立大学农业研究中心于2019年3月开发并发布了``Stingray CL +''（注册号CV-1117，PI 691557）SWW小麦。Stingray CL +已通过实验代号MAS100095-2-1-1-S10-1和WA8275 CL +进行了测试，并通过逐代进步进行分配。Stingray CL +是两个基因的超耐受半矮品种，适合华盛顿的高降雨小麦产区。Stingray CL +对条锈病病原体具有高温成年植物的抗性，对于Pch1基因用于秸秆破坏者的脚腐病，对除草剂以外的化学物质具有耐受性，高度中等，季节中期成熟，并且具有较高的粒重和产量。符合国内和出口市场标准的Stingray CL +的最终使用质量属性均可接受。
