摘要 华山新麦草(Psathyrostachys huashanica; 2n=2x=14, NsNs)是小麦(Triticum aesivum)的野生近缘种之一,具有抗多种小麦病害、耐寒抗旱、优质早熟等优良特性,对拓宽小麦遗传基础、创制新种质具有重要利用价值。本文围绕小麦-华山新麦草染色体导入系,汇总了近些年已创制的各类型小麦–华山新麦草衍生系材料,总结了小麦背景中华山新麦草染色体同源群归属的常用鉴定方法,列举了荧光原位杂交实验中适用的Oligo探针,并按同源群梳理了可用的表达序列标签-序列标签位点标记(expressed sequences tags-sequencetagged sites, EST-STS)、简单重复序列(simple sequence repeats, SSR)、特异性片段扩展区域(sequence characterized amplified region, SCAR)、基于PCR的标志性独特基因(PCR-based landmark unique gene, PLUG)和竞争性等位基因特异性PCR (kompetitive allele-specific PCR, KASP)分子标记。此外,分析了华山新麦草遗传物质导入对受体小麦白粉病、条锈病、全蚀病等病害的抗性以及株高、千粒重、分蘖数等农艺性状的影响。最后,对华山新麦草在小麦育种中的应用进行了展望,以期为华山新麦草在小麦遗传育种中的应用提供参考。

AbstractPsathyrostachys huashanica (2n=2x=14, NsNs) is one of the wild relatives of wheat (Triticum aesivum). It has excellent characteristics such as resistance to various wheat diseases, cold and drought tolerance, high quality and early maturity. It has important utilization value for broadening the genetic basis of wheat and creating new germplasm. This article focuses on the wheat-P. huashanica chromosome introgression lines; summarizes the various types of wheat-P. huashanica derived lines that have been created in recent years; and summarizes the common identification methods of P. huashanica chromosome homologous groups in wheat background. The Oligo probes applicable in the fluorescence in situ hybridization experiments were listed, and the available expressed sequences tags-sequencetagged sites (EST-STS), simple sequence repeats (SSR), sequence characterized amplified region (SCAR), PCR-based landmark unique gene (PLUG), and kompetitive allele-specific PCR (KASP) molecular markers were sorted out according to the homologous groups. In addition, the effects of genetic material introgression of P. huashanica on the resistance of receptor wheat to powdery mildew, stripe rust, take-all and other diseases, as well as agronomic traits such as plant height, 1 000-grain weight and tiller number were analyzed. Finally, the application of P. huashanica in wheat breeding was prospected, in order to provide reference for the application of P. huashanica in wheat genetic breeding.
