In the present study conducted at AICRP Maize, University of Agricultural Sciences, Dharwad, sixty single cross hybrids were produced by crossing twenty female inbred lines to three divergent inbred male testers in line x tester design. The parental inbred lines along with test cross hybrids, resistant check, susceptible check and hybrid checks were evaluated for their disease reaction against turcicum leaf blight under artificial epiphytotic condition. Among the inbred lines, TLB-2, TLB-5, TLB-6, TLB-9, TLB-12, TLB-19 and TLB-20 showed resistant reaction against disease. Among the tester CM-111 was moderately resistant, GPM-549 showed moderate susceptibility and GPM-581 was susceptible to disease. Promising female inbred lines such as TLB-6 and TLB-16 produced resistant hybrids irrespective of male testers. Relatively a higher proportion of susceptible hybrids were obtained as two of the three testers were susceptible to disease. The male parent played a crucial role in determining the disease reaction of hybrids.
