| 中文摘要: |
| 为筛选出黄淮麦区抗赤霉病优异品种（系），以黄淮麦区71个主栽小麦品种（系）为材料，于2016-2017和2017-2018两年度采用单花滴注接种的方法，以苏麦3号、郑麦9023、淮麦22和济麦22分别作为抗、中抗、中感和感赤霉病对照品种，在赤霉病重发病区扬州对供试品种（系）进行赤霉病抗性鉴定，同时利用与抗赤霉病基因位点 Fhb1、 Fhb2、 Fhb4、 Fhb5和 QFhs.crc-2DL紧密连锁的分子标记进行基因型分析。结果显示，西农511等5个品种（系）的赤霉病抗性均达到中抗水平，淮麦30等17个品种（系）表现为中感，其他49个品种（系）表现为感病。对照品种苏麦3号同时携带 Fhb1、 Fhb2基因和 QFhs.crc-2DL位点；淮麦40和徐麦DH9可能同时携带 Fhb1基因和 QFhs.crc-2DL位点；太麦198可能携带有 Fhb4基因；明麦16、皖麦32可能携带有 QFhs.crc-2DL位点。有17个赤霉病抗性较好的品种（系）均不携带本研究所检测的抗病基因/QTL。 |
| 英文摘要: |
| Improving Fusarium head blight resistance is one of the major breeding targets in Huang-huai river zone.In order to screen out the excellent cultivars (lines) for FHB resistance breeding,71 cultivars(lines) were evaluated by floret-inoculation method in two years and detected with markers relative to Fhb1, Fhb2, Fhb4, Fhb5 and QFhs.crc-2DL. Sumai 3,Zheng 9023,Huaimai 22 and Jimai 22 were used as high resistant,moderately resistant,moderately susceptible and high susceptible controls for FHB resistance,respectively. The result showed that 5 cultivars(lines) were moderately resistance to FHB,eg. Xinong 511 etc..17 cultivars(lines) were moderately susceptible to FHB,eg.Huaimai 30,etc.. The rest of 49 cultivars were susceptible to FHB. Sumai 3 carries Fhb1, Fhb2 and QFhs.crc-2DL; Huaimai 40 and Xumai DH9 probably carry both Fhb1 and QFhs.crc-2DL; Taimai 198 probably carries Fhb4; Mingmai 16 and Wanmai 32 probably carry QFhs.crc-2DL.There are 17 cultivars (lines) with good resistance but the known FHB resistance genes/QTL have not been detected. |
