| 中文摘要: |
| 小麦赤霉病是由镰刀菌和禾谷镰孢菌引起的小麦真菌病害，严重影响小麦的产量与品质。为了筛选适合黄淮麦区利用的抗病种质资源，于2017-2018年度利用单花滴注对107份黄淮麦区小麦材料进行田间赤霉病抗性鉴定；同时利用与Fhb1、Fhb2、Fhb4和Fhb5共4个与抗赤霉病相关QTL紧密连锁的8个分子标记对供试小麦材料进行了检测。经鉴定，扬富麦101表现为抗赤霉病(R)，宁麦13、宁麦资119、扬麦16等12个品种表现为中抗赤霉病(MR)；分子标记检测发现，这些抗赤霉病品种携带1个或多个抗赤霉病QTL位点，其中Fhb1基因及其基因组合效应最为明显，Fhb1可以作为主要抗性基因应用于小麦赤霉病抗性育种。 |

| Wheat Fusarium head blight(FHB) is a wheat fungal hazard caused by Fusarium and Fusarium graminearum,which seriously affects the yield and quality of wheat. In order to screen the wheat germplasm resistant to FHB,which are suitable for utilization in Huang-Huai River Valley Winter Wheat Region(HHRVWWR),we identified the scab resistance of 107 wheat varieties(lines) from HHRVWWR by single flower instillation method in 2017-2018 growing season.We chose eight molecular markers tightly linked to four QTL loci( Fhb1,Fhb2,Fhb4 and Fhb5) associated with FHB,and tested the resistance sites of the above wheat resources. The results showed that Yangfumai 101 is an FHB(R) tolerant variety,and 12 wheat varieties such as Ningmai 13,Ningmaizi 119 and Yangmai 16 are medium-resistant(MR) varieties. Combined with the results of molecular marker detection,it was found that these resistant varieties carry single or multiple QTL loci.Fhb1 gene and its gene combination effect were most obvious.Fhb1 can be used as a major resistance gene for wheat FHB resistance breeding. |
