Due to the meteorological factors,Henan Province had a large-scale outbreak of corn stalk rot in 2014,and the incidence status of 25 varieties was investigated. According to the relevant resistance identification standards,Xundan509 was classified as resistance variety; Yudan606,Jinsai38 and Xundan3136 were classified as moderate resistance ones,while the other 21 varieties were highly susceptible varieties. Using the yield loss rate of 5% as the critical value of disease tolerance standard,Xundan509,Yudan606,Jinsai38,Xundan3136,Huaiyu5288,Qiaoyu8,XY046,Zhengyu10,Lile66,Weike702 and Xundan29 were classified into tolerance varieties of corn stalk rot. The concept between disease resistance and disease tolerance was distinguished. The diseased plant rate was used as the classification basis of disease resistance and the yield loss rate was used as the evaluation standard of disease tolerance. The relationship between both was showed by a Venn diagram.
