Online Published on 22 January, 2024. Abstract The present investigation was conducted on okra (Abelmoschus esculentus) to determine the extent of heterosis for 12 traits, including fruit yield and its attributing traits. A total of 28 F1s produced by crossing seven lines with four testers of okra in Line x Tester fashion were evaluated along with standard check during late Kharif 2022 season. The cross C20-HRB-55 x Varsha Uphar recorded best heterobeltiosis and the cross C10-VRO-4 x Azad Ganga recorded best standard heterosis for yield plant-1. The cross C10- VRO-4 x Azad Ganga showed negative heterosis over better parent and standard check for the traits days to 50% flowering and days to first picking. The F1 hybrid C10- VRO-4 x Azad Ganga, which has a high potential for yield can be evaluated further for early Kharif season in Punjab.
