Abstract

Forty advanced breeding lines were evaluated for reaction to Groundnut bud necrosis orthotospovirus (GBNV) in the field and greenhouse in Hyderabad, India during2013 rainy season. Results from natural infection showed eight resistant, 24 moderately resistant and eight moderately susceptible genotypes. There were no genotypes pertaining to highly resistant, susceptible and highly susceptible disease reaction grade. Greenhouse screening with mechanical sap inoculation showed all genotypes highly susceptible at 1:10 infected virus extract dilution, whereas at 1:100, two genotypes were moderately resistant, four moderately susceptible, ten susceptible and 24 highly susceptible. There were no genotypes pertaining to highly resistant and resistant disease reaction grade even at 1:100 infected virus extract dilution.
