    摘要:

    利用一套较完整的田间自然感虫鉴定法,对183份小麦品种进行了抗麦红吸浆虫鉴定。鉴定结果表明,小麦不同品种对麦红吸浆虫的抗性存在着显著差异:高抗、中抗、低抗、感虫、高感的小麦品种,分别占参试品种的24.59%、16.94%、18.58%、14.21%、25.68%。不同抗性类型的小麦品种其穗被害率、粒被害率、估计损失率、抗性指数均有较大的差异,其中表现高抗类型45份,中抗类型31份。这些品种既可作为麦红吸浆虫发生区控制麦红吸浆虫危害的主推品种和后备品种,也可作为亲本材料提供给育种单位利用。

    Abstract:

    183 wheat varieties resistant to sitodiplosis mosellana were evaluated in the field. The results showed that there was significant difference among them in resistance of S. mosellana. Highly resistant, moderate resistant, low resistant, susceptible and highly susceptible varieties were 24.59%, 16.94, 18.58%, 14.21% and 25.68%, respectively. There was significant difference in ratio of damaged ear, damaged seed, and estimated damage of different wheat varieties. Among them, the highly resistant, moderate resistante varieties were 45 and 31, respectively. These wheat varieties were valuable as a main extention variety and reserved variety in occured area of S. mosellana or for breeding of resistance varieties.
