| 摘 要： | 为给小麦品种贵州98-18在抗条锈育种中的应用提供参考依据,利用分子标记对贵州98-18的抗条锈性进行了遗传分析。结果表明,在3DS染色体上发现了一个抗条锈基因,暂命名为YrG98。该基因与SSR位点Xgwm161和Xcfd79的连锁距离分别为3.9和4.2cM,很可能是一个新的抗条锈基因。

| Abstract: | Wheat stripe rust,caused by Puccinia striiformis f.sp.tritici,is a major foliar disease,largely influencing the wheat production in China.Identification of stripe rust resistance genes and their closely linked molecular markers is of great importance in breeding resistant wheat cultivars.The objective of this study was to map a stripe rust resistance gene in wheat line Guizhou 98-18 using molecular markers.The stripe rust resistance gene,designated as YrG98 tentatively,was located on chromosome 3DS,and linked to the SSR loci Xgwm161 and Xcfd79,with genetic distances of 3.9 cM and 4.2 cM,respectively,which is likely to be a new gene for stripe rust resistance.This study will provide an useful stripe rust resistance gene and its closely linked molecular markers for wheat breeding. |
