Field Evaluation of Brinjal Genotypes for Resistance to Brinjal Shoot and Fruit Borer, Leucinodes orbonalis Guenee

Response of different brinjal genotypes against brinjal shoot and fruit borer (Leucinodes orbonalis Guenee.) were evaluated at College Farm, N. M.C.A., Navsari Agricultural University, Navsari (Gujarat) in kharif (rainy season) 2013–2014. In present investigation it observed that none of the screened genotypes was found immune to L. orbonalis. The shoot infestation on various genotypes ranged from 4.00 to 15.50 per cent. The genotype AB7–2 recorded significantly lowest shoot damage (4.90%) whereas, significantly highest shoot infestation observed in genotype JBGR 1 which had 15.50 per cent. In case of fruit damage on number and weight basis genotype AB 7–2 found to be resistance which noted 7.57 and 7.44 per cent infestation, respectively. However the highest infestation found on genotype JBGR 1 which noted 44.32 per cent on number basis and 44.15 per cent on weight basis. Remaining genotypes ranged between 8.82 to 42.17 per cent (on number basis) and 9.03 to 42.14 per cent (on weight basis).
