A total of 40 germplasm of brinjal were evaluated for their reaction against fruit and shoot borer, Leucinodes orbonalis Guen. The infestation of shoot borer appeared in 43 rd week (18-24 October). The shoot infestation mean varied between 0 to 20 %. Six genotypes viz. General Equilibrium position of fruit borer varied between 14.18 to 53.19% fruit infestation on different genotypes. Minimum fruit infestation being 14.18% was observed on germplasm HMB-10, followed by 18.54, 24.01, 24.07 and 24.29% fruit infestation on SM-195, Long Green Mysore, Pant Samrat and S-15-1 genotypes, respectively. Maximum infestation of 53.19% was noticed on H-129. The essence of result of germplasm screening against brinjal shoot and fruit borer revealed that HMB-10, Pant Samrat, SM-195, Pusa Purple Long, S-15-1, H-165, Long Green Mysore and S-10-1 showed resistant/ moderately resistant reaction to this pest. It was observed that shape index has significant negative association with fruity infestation (r=0.32), whereas thickness of mesocarp was positively significantly correlated (r=0.511).
