Rice Blast caused by the fungal pathogen Magnaporthe oryzae is one of the most devastating diseases worldwide. Host plant resistance is the effective and economical way to manage this disease. Host plant resistance has been exploited as source for developing resistant variety since past. Challenge (host resistance) induced shifts in pathogen variabilities necessitates continuous development of need based resistant varieties. Knowledge on ever-changing and location specific variability pattern of pathogen, with reference to known, available blast resistant genes, is prerequisite for such efforts. | Identification of broad spectrum blast resistance genes for north-east and eastern India using standard international blast differentia
