Maydis leaf blight is considered the most devastating disease of maize crop, which causes noticeable reduction in crop yield. The present studies were undertaken to find out the stable sources of maydis leaf blight resistance. A set was obtained by crossing ten QPM inbred lines in 10×10 half diallel fashion excluding reciprocals. In total sixty lines including parents, F1’s and standard check (HQPM-1, HQPM-4, HQPM-7, PRATAP QPM-1 and VIVEK QPM-9) were evaluated against leaf blight (Exserohilum turcicum) of maize under field conditions during kharif 2016 and 2017. One QPM inbred CML162, two QPM check VIVEK QPM-9, HQPM-1 and 17 hybrids viz., CML189 × CML163, CML180 × CML170, CML193 × CML170, CML170 × CML163, BAJIMQ-08-26 × CML189, BAJIMQ-08-27 × CML171, CML180 × BAJIMQ-08-27, CML193 × CML171, CML180 × CML163, CML170 × CML161, CML189 × CML162, CML193 × CML163, CML180 × BAJIMQ-08-26, CML193 × BAJIMQ-08-26, CML189 × CML171, BAJIMQ-08-26 × CML170, CML180 × CML162 showed resistant reaction against maydis leaf blight. Twenty three crosses, seven parents and two checks were found moderately resistant and five crosses one QPM check and two inbreds were found moderately susceptible Thus, the identified resistant genotypes could be utilized for developing promising maize hybrids with inbuilt resistance to maydis leaf blight disease of maize.
