Abstract：Based on multi-spectral remote sensing technology，this study scaned potato experimental field at low altitude using multi-spectral camera PARROT SEQUOIA on UAV platform；and identified the growth situation of potato varieties（lines）under disease stress．This study also conducted correlation analysis both on the early blight disease index of 21 varieties（lines）obtained by manual investigation，and NDVI data gained by scanning analysis．The results showed that NDVI data had extrem significant negative correlation with disease index，and the correlation coefficient was -0.973．The coefficient of determination（R2 value）in the linear regression analysis was 0.947．Therefore，it is confirmed that multispectral remote sensing technology can be applied to identify potato varieties（lines）resistance to early blight；and also improve the investigation efficiency．
