Over thirty publications during the last 10 years have identified more than 140 QTLs for stripe rust resistance in wheat. It is likely that many of these QTLs are identical genes that have been spread through plant breeding into diverse backgrounds through phenotypic selection under stripe rust epidemics. Allelism testing can be used to differentiate genes in similar locations but in different genetic backgrounds; however, this is problematic for QTL studies where multiple loci segregate from any one parent. This review utilizes consensus maps to illustrate important genomic regions that have had effects against stripe rust in wheat, and although this methodology cannot distinguish alleles from closely linked genes, it does highlight the extent of genetic diversity for this trait and identifies the most valuable loci and the parents possessing them for utilization in breeding programs. With the advent of cheaper, high throughput genotyping technologies, it is envisioned that there will be many more publications in the near future describing ever more QTLs. This review sets the scene for the coming influx of data and will quickly enable researchers to identify new loci in their given populations.
在过去的 10 年中，已有超过 30 篇出版物确定了小麦抗条锈病的 140 多个数量性状位点（QTL）。很可能其中许多 QTL 是相同的基因，通过表型选择在条锈病流行期间在不同的背景下通过植物育种传播到不同的背景中。等位基因测试可用于区分相似位置但在不同遗传背景下的基因；然而，对于从任何一个亲本中分离出多个基因座的 QTL 研究来说，这是有问题的。本综述利用共识图谱来说明对小麦条锈病有影响的重要基因组区域，尽管这种方法不能区分紧密连锁基因的等位基因，但它确实突出了该性状的遗传多样性程度，并确定了最有价值的基因座及其携带这些基因座的亲本，以用于育种计划。随着更便宜、高通量基因分型技术的出现，可以预见在不久的将来会有更多的出版物描述更多的 QTL。本综述为即将涌入的大量数据奠定了基础，并将使研究人员能够快速识别其特定群体中的新基因座。
