- Abstract
A field experiment was carried out to screen the sorghum genotypes against stem borer in rice fallow under zero tillage condition. Based on mean stem tunnel length, the genotypes were categorized as least susceptible (0-5 cm), moderately susceptible (5-10 cm) and highly susceptible (>10 cm). The resistant check CSH 16 (C) was found least susceptible with 4.65 cm, whereas NTJ-2 (C), NLCW-6 and N-14 were found to be highly susceptible as they recorded 10.45, 10.46 and 11.44 cm mean stem tunnel length respectively. The remaining genotypes were moderately susceptible with 6.60-9.84 cm mean stem tunnel length. There was non-significant positive correlation between the number of larvae and leaf damage, dead hearts, stem tunnelling, white ears and chaffy grains respectively, but it was negative for tiller damage.
