摘要
Abstract
To explore the disease resistance level of corn varieties in Ningxia,an analysis and study on the disease resistance of 88 new corn varieties approved in Ningxia from 2021 to 2023 was conducted.The results showed that the proportions of the 88 approved new corn varieties with resistance(HR,MR And R)to common diseases-stalk rot,ear rot,northern leaf blight,head smut,common rust,and southern leaf blight were 82.95%,48.86%,14.77%,23.86%,38.64%and 6.82%respectively,while the proportions susceptible(HS and S)were 17.05%,37.5%,85.23%,75%,50%and 1.14%respectively.There were 64 varieties that are resistant to two or more diseases simultaneously,accounting for 72.73%of the approved varieties,mainly showing resistance to both stalk rot and ear rot.There were 77 varieties susceptible to two or more diseases,accounting for 87.5%of the approved varieties,mainly showing susceptibility to both northern leaf blight and head smut.Overall,the 88 new maize varieties approved in Ningxia from 2021 to 2023 had certain resistance to stalk rot and ear rot but poor resistance to northern leaf blight and common rust.关键词
