Screening of a set of 12 different composite and commercial hybrid varieties/land races against Turcicum leaf blight disease showed differences in disease reaction. These varieties differed significantly and Percent Disease index (PDI) ranged from 10 to 62%. Among the different varieties, Allrounder, Prabal, DKC- 9081 showed significantly less (P=0.05) disease as compared to other varieties. Keeping this in mind, they were classified as Tolerant Type and Susceptible Type. The studies on leaf structural anatomy of the both the types reveled that difference in number of stomata per unit area, size of vascular bundle, lower and upper epidermis and number of trichomes per unit area. It may be concluded that the structural anatomy of maize leaf may play an important role in resistance and susceptibility to the Turcicum leaf blight disease.
