Abstract
Heterosis was studied for yield and its component traits in eight parental lines and 28 F1 hybrids obtained from 8 × 8 half diallel cross excluding reciprocals in randomized block design (RBD) with three replication. P4 (Pusa Uday), P6 (DC-1) and P5 (Punjab Naveen) were observed to be three best performing parents for total yield per plant. Appreciable heterosis was recorded over standard check (Pusa Uday) for all the traits studied except for fruit width. Three best performing hybrids were Pusa Uday × DC-1 followed by Pusa Uday × Kalyanpur Green and Pusa Uday × Punjab Naveen which showed significant heterosis of 86, 62.9 and 56.11%, respectively over standard parent for yield and other desirable traits and these hybrid combinations may be exploited for commercial cultivation.
