‘Mela CL+’ (Reg. no. CV‐1157, PI 675008; PVP 201500291) is a soft white common winter wheat (Triticum aestivum L.) cultivar carrying two‐gene tolerance to imazamox herbicide, also known as Clearfield Plus, that was developed and released by the Agricultural Research Center, Washington State University, in October 2013. It was tested under the experimental designations EBC2F3‐3‐20 and WA008155. Mela CL+ was developed using a marker‐assisted backcross selection method involving a cross between the soft white winter (SWW) wheat cultivar ‘Eltan’ and CL0618, an Australian hard red spring line carrying the two‐gene Clearfield technology. The two‐gene Clearfield technology present in Mela CL+ was due to two mutation alleles Als1 and Als2 of the acetolactate synthase (ALS) gene copies located on the long arm of chromosomes 6B and 6D. Mela CL+ has high grain yield potential and intermediate plant height and is well adapted to the dryland production areas of the Pacific Northwest (PNW) with <300 mm of annual precipitation. Tested in multiple locations and years, Mela CL+ showed herbicide tolerance equivalent to Clearfield Plus check cultivar ‘AP503 CL2’ and greater tolerance than single‐gene Clearfield cultivars grown in the PNW. Mela CL+ has end‐use quality characteristics similar to cultivars ‘ORCF‐102’, ‘Stephens’, and ‘Xerpha’. As compared to Eltan, Mela CL+ has better stripe rust resistance, whereas the level of snow mold and Cephalosporium stripe tolerance is equal.

注册“ Mela CL +”软白冬小麦

'Mela CL +'(Reg。no。CV-1157,PI 675008; PVP 201500291)是一种柔软的白色普通冬小麦(Triticum aestivum L.)品种,对伊马佐莫克斯除草剂(也称为Clearfield Plus)具有两基因耐受性,即开发和农业研究中心,华盛顿州立大学公布,在2013年10月,它是在实验名称EBC下测试2 ˚F 3 -3-20和WA008155。Mela CL +是使用标记辅助回交选择方法开发的,该方法涉及在软白冬小麦品种'Eltan'和采用双基因Clearfield技术的澳大利亚硬红春线CL0618之间进行杂交。Mela CL +中存在的两基因Clearfield技术是由于两个突变等位基因Als1ALS2的的乙酰乳酸合酶ALS位于染色体6B和6D的长臂)的基因拷贝。Mela CL +具有很高的谷物产量潜力和中等的株高,非常适合西北太平洋(PNW)的旱地生产区,年降水量小于300 mm。在多个地点和年份进行了测试,Mela CL +的除草剂耐受性与Clearfield Plus对照品种'AP503 CL2'相当,并且比PNW中生长的单基因Clearfield品种具有更高的耐受性。Mela CL +的最终使用质量特性类似于'ORCF-102','Stephens'和'Xerpha'品种。与Eltan相比,Mela CL +具有更好的条纹防锈性,而雪霉病的水平和头孢菌条的条纹耐受性相同。
