| 摘 要： | 比较了安徽省主栽品种以及当前推广和将要推广的小麦品种对小麦纹枯病的抗(耐)病性,结果表明:安徽省生产栽培的小麦品种对纹枯病的抗(耐)病性差异显著,但无高抗品种,且抗性差异主要表现为抗扩展的耐病性。根据品种抗性鉴定结果,将安徽省生产栽培的品种分为3类,即:感病类型,以皖麦38、皖麦19、扬麦5号、扬麦158等为代表,相对抗性系数为1.00;中感类型,以皖麦30等为代表,相对抗性系数为0.62;抗病类型,以豫麦18、豫麦21、宁麦9312等为代表,相对抗性系数为0.46。

| Abstract: | The resistant(endurant) difference among 25 wheat commercial and reserve cultivars against wheat sharp eyespot(Rhizoctonia cerealis) in Anhui were compared. The results showed that the resistance of tested cultivars to wheat sharp eyespot had significant difference, but there were no high-resistant cultivars. According to the results, the resistance of all those cultivars to wheat sharp eyespot could be classified into 3 types. The first was susceptible; the second was mid-susceptible; and the third was resistant. The related resistant(endurant) coefficient of susceptible cultivars was 1 and the related resistant(endurant) coefficient of mid-susceptible cultivars and resistant cultivars were 0.62 and 0.46, respectively. |
