Abstract

In this study 15 green gram genotypes were screened for resistance to M. vitrata under field condition. Among 15 genotypes screened against M. virata, IPM-2-K-14-9 and IPM 99-125 showed highest resistance with minimal larval infestation of 0.59 larvae and 0.54 larvae, respectively to pod damage which led to the highest yields of 5.197 and 5.098 q/ha, respectively. SML 668 was found most susceptible, exhibiting 23.24% seed damage and yield of 2.855 q/ha. The result revealed significant genetic variability among the genotypes.
