Identification of blast resistant landraces of North-East India

Result of testing 110 rice landraces from North-east region of India for blast resistance over 2 screenings in the foot-hills of Medziphema, Nagaland, showed 67 resistant,10 moderately resistant/tolerant and the rest susceptible. The resistant entries in the second test exhibited high level(93.1%) consistent resistant reaction. The resistant landraces identified in this study could be utilized in the breeding programme for blast resistant high yielding varieties. Evaluation of resistance to blast disease should be continuously done over location and cropping season.
