To understand the disease resistance of local maize landraces from Southwestern plateau ecological region,the artificial inoculation method was used to evaluate the resistance against northern leaf blight,southern leaf blight and rust.The results showed that there were plenties of disease resistance resources in the tested landraces.Among the 90 landraces,5 were highly resis-tant to rust,13 were highly resistant to southern leaf blight,but non was highly resistant to northern leaf blight though 26 were resistant to the disease.32 of 90 landraces had resistance to all the three diseases(including high resistance,resistance and medium resistance).It is concluded that there exist a lot of disease-resistance germplasms in maize landraces of Southwestern China,which are worth to be used in maize breeding.
