Maize (Zea mays L.) is a major food crop of global importance is greatly affected by turcicum leaf blight commonly called as northern leaf blight caused by fungal pathogen Exserohilum turcicum. The morphological and molecular screening of maize genotypes for resistance against turcicum leaf blight is very crucial in maize crop improvement programme. Morphologically genotypes were classified based on the disease severity as resistance and susceptible genotypes. The molecular screening of genotypes involves use of semi quantitative RT-PCR analysis of relative expression of antifungal genes viz., glucanase and chitinase against turcicum leaf blight infection. This will helps in confirming whether resistance is genotype-dependent than pathogen and effect of multiple factors which induce expression of these anti-fungal genes.The review paper is mainly focused on morphological and molecular screening methods for maize genotypes in comparison with related crop species that will be useful for future maize crop improvement programme.
