Screening of linseed germplasm for resistance against Alternaria spp. cause blight disease in linseed (Linum usitatissimum L.)

Author(s): Narender Kumar and Uma Kant Tripathi
Abstract: A field study was conducted during Rabi, 2015-16 crop seasons at Nwabganj Farm (2014-15) and Oilseed Farm, Kalyanpur, C. S. Azad University of Agriculture and Technology, Kanpur to test the resistance of 200 germplasm against Alternaria spp. under artificial epiphytotic conditions. Each germplasm was sown in second 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 200 genotypes, disease free (F) and highly susceptible (HS) germplasm were not found, 7 genotypes were found resistant (R), 66 were moderately resistant (MR), 102 were moderately susceptible (MS) and 25 were found susceptible (S) against blight disease of linseed.
