Abstract:
Foliar blight disease caused by Drechslera sorokiniana (Sacc) Shoemaker 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, 2018-19 and 2019-20 crop seasons at Wheat pathological Main experiment station at student’s instructional farm, P. G. College Ghazipur and Laboratory of Deptt. of Plant Pathology to test the resistance of 50 Cultivars against Drechslera sorokiniana (Sacc) Shoemaker under artificial epiphytotics conditions. Each cultivar was sown in last week of November in single row of one meter length. Pure culture of Drechslera sorokiniana (Sacc) Shoemaker was inoculated on cultivars 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 50 Cultivars, no any cultivars found immune, 11 cultivars were found resistant, 19 were moderately resistant, 13 were moderately susceptible and 7 were found susceptible against spot blotch disease of wheat.
