Eight hundred and ninety cultivars from North-East India were screened against brown planthopper, Nilparvata lugens (Stāl). Sixty nine entries were identified as resistant or moderately resistant. Most of the donors are from hilly districts of Assam, Meghalaya and from East and South Manipur districts. Age of plant appears to have no influence on the resistance reaction of the test varieties identified from mass screening tests.
