Abstract: Maize is the leading cereal worldwide with wide adaptability and higher productivity potential. It has notable productive potential among the cereals and is the third most important grain crop after wheat and rice. Turcicum leaf blight (TLB) affects the maize crop from the seedling stage to maturity. The present study involved field evaluation of seventy maize landraces for resistance against TLB disease under artificially inoculated field conditions in an augmented design using 3 checks at Mountain Crop Research Station, Larnoo during kharif, 2017. Among seventy landraces, forty-three lines were categorised as resistant, eighteen moderately resistant, five moderately susceptible and landrace Tral 3 recorded highest percent disease index (PDI) as 78.91 per cent and rated as susceptible. Thus the genotypes identified to possess low disease severity score against TLB would be helpful for their deployment in future breeding programs and eventually could be used in developing promising genotypes having desirable level of resistance in disease endemic areas to aim for sustainable productivity.
