The present study was conducted on four varieties of maize i.e. Local, Sadaf, Sultan and Akbar for resistance against maize stem borer Chilo partellus (Swinhoe) during Kharif 2001. Significant differences were found among genotypes regarding percent infestation, dead hearts, weight of stalks and grains. Sultan was proved to be the most tolerant variety with 8.1% infested plants, 6.46% dead hearts, 51.99 kg stalks and 23 kg grain weight plot-1 followed by Akbar 10.5% infested plants, 48.63% dead hearts 51.09 kg stalks and 22.40 kg grain weight plot-1. Sadaf variety having 11.2% infested plants, 10.63% dead hearts, 49.63 kg stalks and 21.20 kg grain weight plot-1. The results further showed that Local was least tolerant variety with 17.0% infested plants, 12.13% dead hearts, 24.83 kg stalks and 3.2 kg grain weight plot-1.
