Screening of Soybean Genotypes/Varieties for Resistant Against Major Insect-Pests and Classification into Resistance Groups Based on Yield Potential and Loss

Abstract

In search of host plant resistance against defoliators and girdle beetle, thirteen genotypes/varieties of soybean from normal maturity group were screened at Agricultural Research Station, Kota under AICRP on Soybean during kharif 2022. These genotypes/varieties were classified into resistance groups based on their natural yield potential and yield loss due to defoliators and girdle beetle using 'maximin-minimax' method. Accordingly, genotypes NRC 189, NRC 192 and check RVSM 2011-35 as resistant high yielding whereas genotype RSC 11-42 and check AMS 100-39 were tolerant against prevailing insect pest complex. The remaining genotypes/varieties were found susceptible low yielding.
