 ABSTRACT

Among the foliar diseases affecting maize, Turcicum leaf blight (TLB) caused by Exserohilum turcicum is of worldwide importance. In our study, a total of 135 maize genotypes were screened for two years during Kharif season (2014 and 2015) against TLB at Zonal Agricultural Research Station, VC Farm, Mandya.  The mean result of two years screening data on disease severity revealed that, out of 135, none of the genotypes showed resistant, 34 genotypes expressed moderately resistant reaction, 73 showed moderately susceptible reaction and 29 genotypes exhibited susceptibility reaction to TLB disease. The checks 219 J (susceptible check) and Nithyashree (resistant check), showed susceptible and resistant reaction to the disease respectively during two years.

Key words: Maize, Turcicum leaf blight, Exserohilum turcicum, Inbred lines
