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.
