Abstract:

An experiment was undertaken to screen ten promising brinjal genotypes namely BARI Begun-1, BARI Begun-6, BARI Begun-8, BARI Begun-9, BARI Begun-10, BARI F1 Begun-4, Metal Hybrid F1 Begun, Getco Hybrid F1 Begun, local genotypes Singnath and Green ball against Brinjal shoot and fruit borer (BSFB) and to observe their relative level of tolerance and yield performance under natural field conditions in winter (September 2014 to March 2015). The highest fruit yield of 33.32 t ha-1 was harvested from BARI Begun-1 and the lowest 15.63 t ha-1 was obtained from Green ball. The highest and the lowest shoot infestation 17.30% and 7.74% were recorded in BARI Begun-8 and BARI Begun-6, respectively. The lowest fruit infestation by number and weight (20.00% and 18.07%) was found in BARI Begun-1 and the highest fruit infestation by number and weight (42.94% and 42.90%) was observed in BARI Begun-8. Varietal tolerance of brinjal against BSFB indicated significant variations among tested genotypes. The BARI Begun-1 showed the moderate level of tolerance and BARI Begun-8 found to be highly susceptible to BSFB.
