| 摘 要： | 为了解湖北省小麦品种(系)的抗病性水平,对2001年以来湖北省审定的46个小麦品种和在湖北省进行区域试验的447份小麦品系进行赤霉病、条锈病、白粉病和纹枯病等4种主要病害的抗病性评价。结果表明:1)参试品系中有1份材料对赤霉病表现高抗,未发现对纹枯病表现高抗或免疫的材料;对赤霉病和纹枯病的平均抗性评价分值分别为14.30和3.49,介于中感和高感之间;对条锈病和白粉病的平均抗性评价分值分别为13.43和8.34,介于中抗和中感之间。2)审定品种的综合抗性水平不高,对条锈病的抗性评价分值为12.47,介于中抗和中感之间,对其他3种病害的抗性介于中感和高感之间;审定品种的单产呈增加趋势,株高在不断降低,生育期相应延长,综合抗病性也在增强。3)审定品种的综合抗病性与对条锈病抗性的相关系数最高,为0.738;对纹枯病的抗性与株高呈显著正相关,与单产呈显著负相关;对赤霉病的抗性与株高无显著相关。鉴于此,湖北省需加强抗病育种力度,同时应充分做好小麦病害的防控。

| Abstract: | To assess the disease resistance level of wheat varieties (lines) in Hubei province, resistance of 46 wheat varieties authorized in Hubei province and 447 wheat lines tested in regional trials in Hubei since 2001 to four major diseases, including Fusarium head blight (FHB), stripe rust, sharp eyespot and powdery mildew were evaluated. Only one of the tested lines showed high resistance to FHB, and no line was highly resistant or immune to sharp eyespot. The average resistance score of the tested lines against FHB and sharp eyespot were 14.30 and 3.49, respectively, showing moderate to high susceptibility. The average resistance score of the tested lines to stripe rust and powdery mildew were 13.43 and 8.34, respectively, expressing moderate resistance to moderate susceptibility. The comprehensive resistance level of the authorized wheat varieties were not high, it showed moderate resistance to moderate susceptibility to stripe rust with average resistance score of 12.47, and moderate to high susceptibility to the other three diseases. The authorized wheat varieties demonstrated the tendency of increased yield, decreased plant height, extended growth period and enhanced comprehensive disease resistance. The authorized wheat varieties showed the highest correlation coefficient of 0.738 between the comprehensive disease resistance and stripe rust resistance. There are significant positive correlation between sharp eyespot resistance and plant height, and negative correlation between sharp eyespot and yield, while no correlation between FHB resistance and plant height. Thus, to strengthen wheat resistance breeding for disease and management of wheat diseases is necessary in Hubei province. |
