abstract
Fifteen blackgram genotypes were screened for their resistance against spotted pod borer, M. vitrata under field condition at Main Agricultural Research Station, Dharwad. Based on per cent pod damage, The five genotypes, LBG-685 (8.25%), WBU-108 (9.25%), COBG-653 (9.35%), VBN-05 (9.30%) and PU-31(10.10%) were found as tolerant and LBG-631 (32.35%), VBG10-024 (31.60%), RUG-10 (32.85%), KUG-586 (32.80%) and PUSA-9531(31.25%) genotypes showed susceptibility while DU-1(16.85%), DBGV-05 (17.30%), PU-30 (21.35%) and PU-40 (22.35%) were categorized as moderately resistant. The cultivar, COBG-761 (28.15%) exhibited moderately susceptible reaction. The highest per cent infestation of spotted pod borer was registered in the genotype VBG10-024 (69.29%). The lowest number of larval webs were recorded in genotype WBU-108 (1.51webs/Pl) while, the highest was observed in VBG10-024 (5.14 webs/Pl). The maximum pod damage was found in RUG-10 (32.85%) and significantly least pod damage was noticed in LBG-685 (8.25%).
