The present experiment was conducted during autumn-winter seasons 2014-2015 and 2015-2016 at Bidhan Chandra Krishi Viswavidyalaya, West Bengal to study the floral morphology, anthesis-full bloom-anther dehiscense-stigma receptivity, parthenocarpy and other floral characters of eggplant. Twenty one brinjal genotypes were used for this experiment with a randomized block design with three replications. The least time required for flower bud initiation was in the genotype BCB-16 (40.83 DAT) and highest in BCB-1 (58.17 DAT). The maximum days required for 50% plants to be flowered has been reported in BCB-13 (68.33 DAT) and minimum in BCB-22 (50.50 DAT). The highest ratio of (LS+MS): (PS+SS) flowers has been recorded in the genotype BCB-10 (11.52) followed by BCB-8(10.33) and lowest in BCB-11(0.56). Ovary diameter and weight were much higher in the long styled flowers than the rest. Anthesis starts earliest in BCB-18 (6:14 a.m.) and latest by 7:51 a.m. in BCB-11. Full bloom stage generally occurred from 6:50 a.m. (BCB-17) to 8:52 a.m. (BCB-15) and anther dehiscence ranged from 7:00 a.m. (BCB-17) to 9:20 a.m. (BCB-15). Parthenocarpic fruit set was noted only in BCB-6, BCB-11, BCB-14, BCB-15 and BCB-16. The propensity to parthenocarpic fruit set is low in brinjal.
