Online published on 5 February, 2019. Abstract Field screening was carried out during kharif season 2014 and 2015 with 20 varieties/genotypes of blackgram, Vigna mungo (L.) Hepper against spotted pod borer Maruca vitrata. The maximum population of spotted pod borer was observed in genotypes CO5 followed by VBN 4 and Azad 4; the least population was observed with genotypes IPU 94-1, IPU 7–3 and WBC-108 and PU-40 during both years. The maximum pod damage was observed with the genotype VBN 4 followed by CO 5 and LBG 20 and the least with IPU 94-1 and IPU 2–43. The maximum yield was obtained with IPU 94-1 followed by IPU 7–3 and IPU 2–43, and these were resistant. The least yield was obtained with VBN4 and CO 5, and these were highly susceptible.
