Tools for yield prediction are requisite to any successful heterosis breeding program. In this study, heterosis was evaluated by 42 crosses develop by line x tester design (14 lines and 3 testers) along with 2 checks in RBD with 3 replications in wheat for earliness and heat tolerant traits viz.,days to 50 per cent flowering, heat injury, proline content and total chlorophyll content on pooled basis. The pooled analysis for above characters revealed that mean squares due to environments, genotypes, parents, crosses as well as parents v/s. crosses were significant indicating presence of overall heterosis for these traits. Out of forty two crosses, six crosses for days to 50 per cent flowering, 1 cross for heat injury, 2 crosses for proline content and 3 crosses for total chlorophyll content expressed desirable significant better-parent heterosis. In case of economic heterosis, one different cross showed desirable significant economic heterosis for days to 50 per cent flowering, heat injury and proline content.

Keywords: better parent heterosis, economic heterosis, heat tolerant traits, wheat
