Screening of brinjal genotypes resistance against brinjal shoot and fruit borer (Leucinodes orbonalis Guenee)

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.
