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. | Heterosis for earliness and heat tolerant trait in bread wheat [Triticum aestivum (L.)] over the Environments
