Identification of resistance to stripe rust of 10 Chuanmai wheat varieties in Mianyang field

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.
