| 为明确黄淮南片麦区主栽小麦品种对赤霉病的抗性水平。采用人工接种鉴定的方法对黄淮南片的河南、安徽、陕西和江苏四省的65份主栽小麦品种进行赤霉病抗性鉴定, 经土表接种抗侵染型鉴定, 中抗品种有‘徐农0029’、‘西农511’和‘保麦6号’, 中感品种有‘徐麦31’、‘瑞华520’和‘西农3517’等18份, 高感品种44份; 经单花滴注接种抗扩展型鉴定, 中抗品种为‘西农511’, 中感品种有‘烟5158’、‘西农889’、‘西农2000’等14份, 高感品种50份。由此可见, 黄淮南片麦区主栽小麦品种对赤霉病抗性普遍较差, 建议根据各地赤霉病发生程度, 选择适宜抗性指标, 结合现代育种技术, 逐步提高主栽小麦品种的抗性水平。 |
| 英文摘要: |
| To determine the resistance of major wheat cultivars to wheat scab in the south of Huang-Huai wheat zone, 65 varieties were identified by artificial inoculation from Henan, Anhui, Shaanxi and Jiangsu Provinces. The results of field inoculation for resistance to initial infection showed that ‘Xunong0029’, ‘Xinong511’ and ‘Baomai6’ were medium resistant, 18 varieties like ‘Xumai31’, ‘Ruihua520’, ‘Xinong3517’ etc. were medium susceptible, and 44 varieties were highly susceptible. The results of single spike inoculation for resistance to the spread of wheat scab within the spike showed that ‘Xinong511’ was medium resistant, 14 varieties like ‘Yan5158’, ‘Xinong889’, ‘Xinong2000’ etc. were medium susceptible, and 50 varieties were highly susceptible. Therefore, most of major wheat cultivars were susceptible to wheat scab. Wheat varieties resistant to scab should be identified and selected according to occurrence level of wheat scab. Also, modern biological technology should be used in wheat scab resistant breeding. |
