Screening of brinjal genotypes resistance against brinjal shoot and fruit borer (<em>Leucinodes orbonalis</em> Guenee)

Abstract

The present experiment was conducted with fourteen brinjal genotypes from February, 2017 to July, 2017 to identify their characteristics for susceptibility/resistance against brinjal shoot and fruit borer infestation. The shoot infestation mean varied between 23.25 to 56.07%. None of the genotypes were found to be resistant to shoot attack of Leucinodes orbonalis infestation but few genotypes shows tolerant were Arka anand (27.99%), 71-19 × RB-2 (23.25%) and BRBL-02 × BRBL-07 (27.94%). The per cent fruit damage varied from 27.35 to 62.31% and minimum fruit infestation was noticed on genotypes Arka anand (27.35%), 71-19 × RB-2 (27.59%) and BRBL-02 × BRBL-07 (23.58%), whereas, maximum fruit infestation recorded on genotypes Muktakeshi×Swarnmani (54.93) and Pusa hybrid- 9 (62.31%). Among fourteen genotypes, six of them Arka anand, 71-19 x RB-2, BRBL-02 x BRBL-07, RB-2 X BRBL-01, BRBR-01 X RB-2 and BRBL-07 x BRBL-02 were found tolerant, six were found susceptible and rest two genotypes were noticed highly susceptible to brinjal shoot and fruit borer.
