The present study was conducted in the academic year 2016-2017 during kharif season at Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). The screening trial was conducted under two categories, the initial varietal trial (IVT) and advanced varietal trial (AVT). And the entries were screened as per the methodologies explained in the materials and methods. The results on the response of the genotypes in the screening trials are also presented in this paper. During the present study under the IVT trial, genotype PS-1589 with least number of lepidopterous caterpillars per meter row (1.0 number of larvae per meter row) and genotypes NSO-626 with least number of sucking pests per plant (6.0 numbers of sucking pests per plant) were found to be least susceptible against these insect pests. However, the highest yield was recorded with genotypes NRC-126 (675 gm/plot) which was observed and found to be tolerant against different insect-pests in soybean. Under the AVT trial, genotype RV S-2010-1 and RVS-2008-24 with minimum larval count (0.7 larvae per meter row) and genotype DSB-28-3 with minimum sucking pests (11.0 per plant) were identified to be least susceptible against lepidopterous defoliators and sucking pests. The highest grain yield was recorded with genotype PS-1572 (0.976 q/ha) which was found tolerant to against different insect-pests in soybean.
