Abstract:
The present study entitled “Effect of day of emasculation, time of pollination and crossing ratio on seed quality of brinjal hybrid” was conducted in laboratory using the fresh seed harvested from the field experiment using Completely Randomized Design (Factorial) repeated thrice in laboratory of Department of Seed Science and Technology, College of Agriculture, Junagadh Agricultural University, Junagadh during 2019. The study consisted of 18 treatment combinations involving two emasculation days viz., E1: Same day of emasculation, and E2: Previous day of emasculation; three pollination times viz., T1: Pollination between 8:00 am to 9:00 am, T2: Pollination between 9:00 am and 10:00 am, and T3: Pollination between 10:00 to 11:00 am; and three crossing ratios viz., P1: Two female buds pollinated per male flower, P2: Four female buds pollinated per male flower, and P3: Six female buds pollinated per male flower. The previous day of emasculation (E2) produced significantly the higher seed germination (88.48%), seedling vigour index I (493.29) and seedling vigour index II (1058.64). Likewise, pollination during 9.00 am to 10.00 am (T2) recorded significantly more seed germination (86.56%), seedling vigour index I (476.38) and seedling vigour index II (1023.76), while crossing of four female flowers with one male flower (4:1 crossing ratio) (P2) recorded significantly higher seed germination (85.67%), seedling vigour index I (468.05) and seedling vigour index II (1013.37). The higher seed germination (94.33%), seedling vigour index I (556.47) and seedling vigour index II (1160.04) were recorded in E2T2P2 (four female buds pollinated per male flower in previous day of emasculation during 9.00 to 10.00 am).
