FIELD SCREENING OF BRINJAL ACCESSIONS FOR RESISTANCE AGAINST BRINJAL SHOOT AND FRUIT BORER, Leucinodes orbonalis (Lepidoptera: Guenee)

Resistance potential of 100 brinjal accessions against brinjal shoot and fruit borer (BSFB) was evaluated under field condition at Sivapuri village, Chidambaram, Tamil Nadu, India in Kharif 2020. The data obtained from this study revealed that amongst the 100 accessions screened, the lowest shoot and fruit damage was observed on the genotype IC-136546 followed by IC-136451 whereas, the highest shoot and fruit damage was observed on Manapaarai Local followed by IC-089847. Based on the standard scale, none of the accessions show immune response to BSFB. Hence, the accessions which imparted resistance against the BSFB were selected for breeding to develop BSFB resistance varieties.
