The present investigation entitled “Heterosis Analysis in F1 Hybrids of Bread wheat (Triticum aestivum L. em. Thell.) Over Environments” was undertaken using ten genetically diverse parents following diallel mating design excluding reciprocals. The resultant 45 F1s and all the ten parents were evaluated in randomized block design with three replications under three different environments created by three dates of sowing [15 November (E1), 1 December (E2), 15 December (E3)]. Sufficient degree of heterosis and heterobeltiosis was observed for all the attributes. The crosses WH 1021 x PBW 550, Raj 3765 x Raj 3077 and Raj 4238 x WH 1021 in E1; WH 1021 x PBW 550, Raj 3765 x Raj 3077 and DBW 90 x PBW 550 in E2 and WH 1021 x PBW 550, Raj 4238 x WH 1021 and Raj 3765 x HD 3086 in E3 emerged as heterotic as well as heterobeltiotic crosses for grain yield per plant. These crosses were the product of good x good, good x poor or poor x poor general combiners. These crosses were considered promising for their use for yield improvement in wheat. Heterosis and heterobeltiosis were also observed maximum for grain yield per plant.
