The study was conducted with the objective to assess the resistance source against Alternaria blight in rapeseed-mustard at Student's Farm, Chaudhary Charan Singh P.G. College, Heonra, Etawah (U.P.) during Rabi 2006–07. None of the 31 varieties/lines screened against Alternaria blight of the rapeseed-mustard was found immune or highly resistant. The variety NPN1 was found to be resistant with 9.2% incidence of disease. Five genotypes viz. NPC-15, PBC-2004-1, PRQ-2004-1, NDR-03-06 and PR-2003-30 were found to be moderately resistant. Ten lines were found to be moderately susceptible exhibiting 26 to 50% disease incidence. Nine lines were categorized as susceptible (51 to 75% disease incidence) and highly susceptible group comprised of 6 lines. Among all, line NPJ-102 exhibited the highest disease incidence (79.2%).
