Abstract:
An experiment was carried out with eight brinjal germplasms viz; Shinghnath, Tripura Brinjal 10, Bholanath, Tripura Brinjal 17, Tripura Brinjal 8, Tripura Brinjal 21, Tripura Brinjal 4, Tripura Brinjal 18 at Krishi Vigyan Kendra, Khowai, Tripura to find out the suitable resistant germplasms against brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis Guen. The data on fruit damage revealed that significantly lowest fruit damage (17.34%) was recorded in the germplasm Shingnath, in comparison to Tripura Brinjal 18 which recorded the highest mean infestation value (45.38%) of L. orbonalis on number basis. Similarly, significant lowest fruit damage on weight basis was recorded in the germplasm Shingnath (14.08%) which was at par with Tripura Brinjal 10 (17.73%) and the highest fruit damage was observed in the germplasm Tripura Brinjal 18 (42.40%). The descending order of fruit infestation of L. orbonalis to different brinjal germplasms was Shingnath< Tripura Brinjal 10< Tripura Brinjal 17< Bholanath< Tripura Brinjal 8< Tripura Brinjal 21< Tripura Brinjal 4< Tripura Brinjal 18. Significantly highest fruit yield (19.46 tonnes/ha) was recorded in germplasm Shingnath and lowest (5.47 tonnes/ha) fruit yield was obtained in highly susceptible germplasms Tripura Brinjal 18.
