Foliar blight disease caused by Bipolaris sorokiniana (Sacc.) Shoem is most important disease of wheat in North Eastern plain zones (NEPZ) representing warm and humid climate in India. It is also increasing in North Western plains zones (NWPZ), due to climate changes and causes considerable losses in susceptible varieties. A field study was conducted during Rabi, 2014-15 and 2015-16 crop seasons at Main Experiment Station, Narendradev University of Agriculture and Technology, Kumarganj, Faizabad to test the resistance of 250 genotypes against Bipolaris sorokiniana under artificial epiphytotics 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 Bipolaris sorokiniana 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 300 genotypes, no any genotype found immune, 29 genotypes were found resistant, 132 were moderately resistant, 103 were moderately susceptible and 37 were found susceptible against spot blotch disease of wheat.
