摘　　要：水稻白叶枯病一旦发生极难防治,为筛选出适合在白叶枯病发生区种植的杂交水稻抗性品种,选择仙居县主栽的7个杂交水稻品种,在下各镇病区开展小区试验。结果显示,甬优12号和浙优18在药剂防控的条件下表现较好,病叶率低于80%、病情指数15.0左右,产量达到10.50 t/hm^(2)以上,相对适合在病区种植;中浙优8号(CK)表现极感病,产量损失严重,不适合在病区种植。It is very difficult to control rice bacterial leaf blight once it occurs.To screen out the resistant hybrid rice varieties suitable for planting in the areas where rice bacterial leaf blight occurs,seven hybrid rice varieties mainly planted in Xianju County were selected to carry out the plot experiment in the endemic areas of Xiage Town.The results showed that Yongyou 12 and Zheyou 18 had a good performance under the condition of pesticide prevention and control with the diseased leaf rate less than 80%,the disease index at about 15.0 and the yield above 10.50 t/hm^(2),which was relatively suitable for planting in diseased areas.Zhongzheyou 8(CK)showed extreme susceptibility and serious yield loss and was not suitable for planting in diseased areas.
