Abstract
In a field condition, 100 brinjal accessions were screened at Sivapuri village, Tamil Nadu, India in Rabi 2021 to observe their resistance potential to brinjal shoot and fruit borer, L. orbonalis. The results acquired during the Rabi 2021 field screening, revealed that shoot and fruit damage differed notably across brinjal accessions. It was observed that IC-136546 had the lowest shoot and fruit damage followed by IC-136451, while Manapaarai Local had the highest shoot and fruit damage, followed by IC-089847. Based on per cent fruit damage, 9 accessions were highly resistant, 14 were moderately resistant, 25 were tolerant, 31 were susceptible and 21 were highly susceptible and none of the accession was showed immune response to brinjal shoot and fruit borer. As a result, accessions that categorized under the resistance were chosen for further evaluation in order to develop promising varieties.
