The experiment was conducted with 55 eggplant hybrids derived from 11 x 11 half diallel crosses along with standard variety at the field 10 and field 15 of University of Putra Malaysia (Serdang, Selangor, Malaysia) at one season during November 2020 to January 2021. The aim of this research was to develop high yield and quality eggplant hybrids. This research was followed by randomised complete block design with three replications at two locations. 15 morphological and biochemical traits were estimated for heterosis. Among these, BM9 x BB26 was chosen as the best hybrid for yield per plant considering standard heterosis, heterobeltosis and relative heterosis. Besides, BB1 x BT15 hybrid was also the best for total soluble solid over check variety and BT6 x BT15 was the best for total phenol content considering all three types of heterosis i.e. relative heterosis, heterobeltosis and standard heterosis. Conversely, the highest value for heterobeltosis and relative heterosis was found in the hybrid BM5 x BT15 and the hybrid BM9 x BB23 was the best over standard heterosis for DPPH of antioxidant activity. Hence, these two hybrids could be considered to get higher antioxidant activity in eggplants. The breeders, agronomists, and horticulturists can use these results to select the best hybrids for further practical research
