Among fifteen maize genotypes evaluated for their reaction to stem borers, the hybrids, Super 900M and Bioseed 9681 were found less susceptible to Chilo partellus and Sesamia inferens, while, NK 6240, NK 30 and Arjun were highly susceptible in terms of leaf feeding score and per cent infestation. Correlation of trichome density and leaf width with per cent infestation of stem borers was significantly positive. However, the correlation between other morphological characters and borer damage were non-significant.
