The field experiment was conducted during Kharif 2020 at Saheed Gundadhur College of Agriculture and Research Station, Jagdalpur, IGKV, Raipur (CG), to identify the resistant genotypes for blast disease (Magnaporthe grisea). Under an initial varietal trail were twenty-seven genotypes evaluated with one resistant (GE4449) and susceptible (Udru mallige) check varieties and found that all genotypes were promising for leaf blast resistant where show the leaf blast range between 1.67 to 3.67 G. Genotype PR1731 found highly resistant and OEB 610 (7.24%), GPU 103 (7.56%), PPR 1096 (9.44%) and KMR 702 (4.95%) was recorded promising to resistant for neck blast and maximum severity was observed in RAUF-25 (34.60%). For finger blast all the genotype were found to be resistant and severity range between 1.04 to 6.81%. This experiment was carried out in seven different location of India and the mean of all seven-location revealed that the incidence ranged from 2.72 to 5.03 G in leaf blast and 13.01 to 34.4% and 7 to 21.23 % for neck blast and finger blast respectively. All the entries were show resistant to moderately resistant for leaf blast, neck blast and finger blast only IIMR-FM 3001 susceptible for finger blast
