‘Curiosity CL+’ (Reg. no. CV‐1167, PI 675007; PVP 201500290) is a soft white winter (SWW) wheat (Triticum aestivum L.) cultivar carrying two‐gene tolerance to imazamox herbicide that was developed and released by the Agricultural Research Center of Washington State University in October 2013. It was tested under the experimental designations EBC₂F₃‐3‐18 and WA008143. Curiosity CL+ was developed using marker‐assisted background selection involving a cross between ‘Eltan’ and ‘CL0618’. Eltan was a predominant SWW wheat cultivar (released in 1990) in the Pacific Northwest (PNW), whereas CL0618 is an Australian hard red spring line carrying two‐gene mutations conferring herbicide tolerance. Curiosity CL+ carries two mutation alleles (AhasL‐B1 and AhasL‐D1) of acetolactate synthase gene copies on chromosomes 6B and 6D. Curiosity CL+ has high grain‐yield potential, intermediate plant height, and is well adapted to the dryland production areas of the PNW with <300 mm of annual precipitation. Tested in multiple location and years, Curiosity CL+ showed herbicide tolerance equivalent to the two‐gene Clearfield cultivar ‘AP503 CL2’ (PVP 200800322) and higher than the single‐gene Clearfield cultivar ‘ORCF‐102’ (PI 641787). Its end‐use quality is similar to ORCF‐102, ‘Stephens’ (CI 17596), and ‘Xerpha’ (PI 645605). Compared with Eltan, Curiosity CL+ has better stripe rust resistance, whereas the level of snow mold and Cephalosporium stripe tolerance is equal.

“ Curiosity CL +”软白冬小麦的注册

'Curiosity CL +'（Reg。no。CV-1167，PI 675007; PVP 201500290）是一种软白冬小麦（Triticum aestivum L.）品种，对玉米粉虱除草剂具有两个基因的耐受性，由该品种开发并释放。在2013年10月，美国华盛顿州立大学的农业研究中心实验名称下测试EBC ₂ ˚F ₃ -3-18和WA008143。好奇心CL +是使用标记辅助背景选择开发的，涉及“ Eltan”和“ CL0618”之间的杂交。Eltan是太平洋西北地区（PNW）的主要SWW小麦品种（1990年发布），而CL0618是澳大利亚的硬红春系，带有两个基因突变，赋予除草剂耐受性。好奇心CL +携带两个突变等位基因（AhasL-B1和6a和6D染色体上乙酰乳酸合酶基因拷贝的AhasL‐D1）。好奇心CL +具有较高的单产潜力，株高中等，非常适合PNW的旱地生产区，年降水量小于300 mm。经过多地点和多年的测试，Curiocity CL +对除草剂的耐受性与两个基因的Clearfield品种'AP503 CL2'（PVP 200800322）相当，并且高于单个基因的Clearfield品种'ORCF-102'（PI 641787）。其最终使用质量类似于ORCF-102，“ Stephens”（CI 17596）和“ Xerpha”（PI 645605）。与Eltan相比，Curiocity CL +具有更好的条纹防锈性能，而雪霉病水平和头孢属条纹耐受性则相同。
