Abstract: Stemphylium blight, caused by the fungal pathogen Stemphylium botryosum, is one of the important diseases in lentil, an important rabi pulse grown in the plains of West Bengal. Considering the severity of the disease in the existing cropping system, an experiment was undertaken with the objective to study the change in the patterns of various biotic stress related biomolecules among fifty (50) lentil genotypes under the incidence of Stemphylium blight. The genotype IC620839 recorded the lowest PDI (11.25) with the AUDPC score of 202.41 while IC54456 had the highest PDI (79.37) and AUDPC score (1598.60), respectively. The genotype IC241072 with the lowest disease score (1.5) and PDI (11.87) along with the highest Ortho-Dihydric Phenol and Super Oxide Dismutase content under artificial inoculum was in a separate cluster. The observation could thus be helpful in the future crop improvement schemes as far as disease resistance in lentil is concerned.
