The highest chlorophyll 'a' content was recorded in the variety BLO 101 (0.74) and was found significantly different from other varieties/lines except BLO 114 and khotkhotia-1. The lowest amount of chlorophyll 'a' content was observed in the variety Nayankajal (0.431, which was also significantly different from that of other varieties/lines. The chlorophyll 'a' content was negatively correlated (-0.146) with brinjal shoot and fruit borer (BSFBI infestation. The highest chlorophyll 'b' content was recorded at 70 DA T. The amount of chlorophyll 'b' varied significantly among the varieties/lines at different ages. The lowest chlorophyll 'b' content was recorded at 40 DAT (0.261 and it was statistically identical with that of 100 DAT (0.301. The average highest amount of chlorophyll 'b' was estimated in the variety Dhohazari-1 (0.451, which was significantly different from that of other varietiesllines except BLO 45. The lowest amount of chlorophyll 'b' was obtained in the variety Laffa (0.251, which was significantly different from that of all other varieties/lines. The highest amount of total chlorophyll contents was estimated in the variety BLO 114 (1.109) which was significantly different from that of other varieties/lines. The average lowest amount of total chlorophyll was estimated in the variety Nayankajal (0.83) vvith the highest infestation.
