Abstract
The study was conducted during the Kharif season of 2024 at the
College of Horticulture, Bengaluru, Karnataka, India, focusing on the okra
population derived from the cross OK-2017-010 × Varsha Uphar. Among the
segregants, a notable frequency was observed for key traits: 40.42% of
segregants exhibited increased numbers of branches, 50.42% showed increased
numbers of nodes and 55% displayed earlier days to first flowering. The simultaneous transgressive segregant shows the highest for the combined favorable attributes, including a higher number of nodes,
increased branches and number of fruits per plant, which collectively
contributed to its enhanced productivity. Significantly, the transgressive
segregant identified as "T" recorded the highest yield increase,
achieving a remarkable 64.21% improvement compared to the parent. The
findings underscore the potential of transgressive segregants for achieving
substantial yield improvements in okra through the synergistic enhancement of
critical traits, emphasizing their value in breeding programs aimed at
maximizing genetic gain.
