Screening of different groundnut genotypes/varieties against Spodoptera litura (Fab.)

A field experiment was conducted at the Main Oilseeds Research Station, Junagadh Agricultural University, Junagadh, Gujarat, India in 2023 during the kharif season to screen different groundnut genotypes/varieties against Spodoptera litura (Fab.). The field screening of 30 different genotypes/varieties of groundnut against S. litura revealed that JVB-2597 exhibited the lowest number of larvae (0.55 larvae/plant), while JVB-2577 showed the highest infestation level (2.01 larvae/plant). From the categorization, it was revealed that JVB-2597, JSSP-76, JB-1572, J-108 and JVB-2607 are resistant to S. litura, with infestation ranging from 0.53 to 0.90 larvae per plant. Conversely, JSSP-69, JB-1585, J-118, J-111 and JVB-2577 are susceptible, by recording infestation levels between 1.75 to 2.01 larvae per plant.
