The present study was carried out at AB District Seed Farm, BCKV, Kalyani Simanta, West Bengal, India during spring-summer 2012-13 and 2013-14, autumn-winter 2013-14 and 2014-15 with 40 brinjal genotypes in Randomized Block Design with two replications. Highly significant differences were observed for majority of the characters for the two factors viz., genotypes (G) and season (S) and their interaction (G X S). Paired t-test also clearly demonstrated the influence of season on the performance of eggplant germplasm. The vegetative phage was favoured and earlier flowering took place during spring summer and the reproductive phage was favoured during autumn winter. The characters plant height and primary branches per plant were high and the genotypes took less number of days for flowering during spring summer. Other important yield components like number of fruits per plant, fruit weight, fruit yield per plant and harvesting index were high during autumn winter.
