The Louise‐Penawawa spring wheat (Triticum aestivum L.) recombinant inbred line (RIL) mapping population (Reg. no. MP‐13, NSL 535038 MAP) was developed from a cross between the elite soft white spring wheat cultivars ‘Louise’ and ‘Penawawa’ at Washington State University. The population is composed of 180 RILs developed through single seed descent from the F₂ to the F₅ generation. The population and its parents were genotyped using both simple sequence repeat and single‐nucleotide polymorphism marker platforms. Analysis of markers identified 29 linkage groups that located to all 21 wheat chromosomes. The population was initially developed for the study of high‐temperature adult‐plant stripe rust resistance but has since been phenotyped and used to identify Hessian fly resistance, tan spot resistance, polyphenol oxidase activity, vital agronomic traits, and milling and baking quality. Markers have been identified that are closely linked with quantitative trait loci (QTL) that influence these traits. This population has the potential to identify QTL for additional traits of interest. Additionally, lines from this RIL population are well suited to introgress traits of interest as both Louise and Penawawa are commercially released cultivars adapted to a variety of growing regions and conditions.

Louise-Penawawa春小麦重组自交系作图群体的注册

Louise-Penawawa春小麦（Triticum aestivum L.）重组自交系（RIL）作图群体（Reg。no。MP-13，NSL 535038 MAP）是由优良的软白春小麦品种'Louise'和华盛顿州立大学的“ Penawawa”。种群由从F ₂到F _5的单种子后代发育的180个RIL组成代。使用简单的序列重复和单核苷酸多态性标记平台对人群及其亲本进行基因分型。标记分析确定了位于所有21个小麦染色体上的29个连锁群。该种群最初是为研究高温成年植物条纹锈病而开发的，但此后进行了表型分析，并用于鉴定黑森州的抗蝇性，棕褐色斑点抗性，多酚氧化酶活性，重要的农艺性状以及制粉和烘烤质量。已经鉴定出与影响这些性状的数量性状基因座（QTL）紧密相关的标记。该人群有可能识别其他感兴趣特征的QTL。另外，
