摘　　要：选用2006—2010年通过四川省农作物品种审定的10个川麦系列小麦品种,通过大田自然诱发,对其成株期不同生育期的抗锈性进行鉴定分析,旨在筛选出具有免疫及高抗的品种。方差分析结果表明,不同品种普遍率以及严重度的差异显著,部分川麦系列品种病情指数有显著差异。综合分析表明,川麦53、川麦48、川麦54表现为近免疫,川麦55、川麦58表现为高抗,川麦56表现为中抗,其余表现为中感。相关性分析表明,不同抗性组分之间均表现为极显著相关。表明在生产中不能忽视任何一个因素,一旦发现条锈病,应立即进行防治,防止条锈病的加重与蔓延。In this experiment,10 varieties of wheat and wheat cultivars approved by Sichuan Provincial Crop Variety Approval Committee in 2006-2010 were used to identify the rust resistance at different growth stages,to screen out the varieties with immunity and high resistance.The variance analysis showed that the prevalence of different varieties was significantly different,and the disease index of some Chuanmai varieties was significantly different.The comprehensive analysis showed that Chuanmai 53,Chuanmai 48 and Chuanmai 54 showed nearly immunization.Chuanmai 55 and Chuanmai 58 showed high resistance.Chuanmai 56 showed neutral resistance,and the rest showed medium sensation.The correlation analysis showed that there was a significant correlation between the different resistant components,indicating that we can not ignore any factor in the production,once we found rust,it should be immediately to prevent and control,to prevent the increase and spread of stripe rust.
