Abstract:
Brinjal shoot and fruit borer (BSFB) Leucinodes orbonalis Guenee is a major pest of brinjal which primarily attacks the shoot and fruits of brinjal. An experiment was undertaken to screen the different brinjal genotypes at Varanasi against BSFB and to observe their relative level of resistance under natural field conditions in during 2017 and 2018. The parameters like percent shoot and fruit infestation caused by BSFB and the further damage scale reported was selected for screening the different brinjal genotypes. The genotypes selection-10 showed least shoot (20.1 and 29.8%) and fruit (12.7 and 6.4%) infestation. The genotype CHBR-2 showed higher shoot infestation (38.4 and 32.2%) but lower fruit infestation (18.7 and 21.4%). The higher shoot and fruit infestation was observed in the genotypes Punjab Sadabahar, Kashi Taru, Kashi Sandesh, Pant Rituraj and Kashi Uttam. The genotype Selection-10 can be deployed in the resistance breeding programme against BSFB, Leucinodes orbonalis.
