Maydis leaf blight is a serious foliar fungal disease of maize, may cause up to 41 per cent losses in grain yield. The present studies were undertaken to find out the stable sources of maydis leaf blight resistance. A set of one hundred and two maize inbred lines were evaluated against maydis leaf blight incited by Bipolaris maydis under artificial epiphytotic conditions at Regional Research Station, Karnal, CCSHAU during Kharif 2015 and 2016. The incidence of maydis leaf blight was recorded following 1-5 rating scale and the genotypes evaluated were grouped into four categories viz. resistant, moderately resistant, moderately susceptible and susceptible based on their disease reaction. Our results indicated that six genotypes (HKI 1128, HKI 5072-2BT (1-2-2), HKI 1352-58-9, MBR-139, HKI 190 and HKI 1352-58-9-2) were found resistant, thirty six genotypes were moderately resistant, fifty genotypes showed moderately susceptible reaction and ten exhibited susceptible reaction against maydis leaf blight. Thus, the identified six resistant genotypes could be utilized for developing promising maize hybrids with inbuilt resistance to maydis leaf blight disease of maize.
