Abstract
A set of 105 peanut germplasm were evaluated against late leaf spot during kharif 2021 at Main Agricultural Research Station, University of Agricultural Sciences, Raichur. The experiment was laid out in Augmented random block design. Data on LLS disease severity was collected using modified 1 to 9 point scale at 65, 85 and 105 days after sowing (DAS). Study revealed that, none of the genotype showed resistant reaction, 12 genotypes were moderate resistant, 40 genotypes were susceptible and 53 genotypes were found to be highly susceptible to LLS.
