A field study was conducted during Rabi, 2014-15 and 2015-16 crop seasons at Main Experiment Station, NDUA & T, Kumarganj, Faizabad to test the resistance of 176 genotypes against Bipolaris sorokiniana under artificial epiphytotic conditions. Each genotype was sown in last week of November in single row of one meter length. Variety Raj 4015 was used as check and was sown after every 20 genotypes. Pure culture of pathogen was inoculated on genotypes by using cleaned sprayer, at evening. Disease data was recorded using double digit scale based on per cent blighted area on flag leaf and one leaf just below. Out of 176 genotypes, one namely KARAWANI/4NIF3/SOTY/NAD63/CHRIS was found immune, 31 genotypes were found resistant, 75 were moderately resistant, 52 were moderately susceptible and 17 were found susceptible against spot blotch disease of wheat.
