Out of 26 genotypes screened against root borer (Emmalocera depressella, Swinhoe), 5 genotypes (CoH-84, CoH 89, CoH 56, S 87/15 and S 87/256) were categorized as moderately resistance. 3 genotypes (Co 1148, S 85/314 and S 85/94) were graded as highly susceptible, as the larval population and corresponding incidence were highest in these varieties'. The mean larval population and incidence of root borer in moderately resistant varieties ranged from 10–20 thousands/ha and 20 to 27.8 per cent, respectively. Whereas, in susceptible varieties population and incidence ranged from 121.60 to 180.00 thousands/ha and 62.45 to 67.40 per cent, respectively.
