Abstract: Line x tester analysis was carried out with the objective of to find out the superior combinations of parents giving high degree of useful heterosis for fruit yield and its contributing characters and for future use in the breeding programme. Significant and desired directional heterosis was observed for majority of the yield attributing trits for fruit yield per plant in okra. Experimental material comprising twelve parents and their thirty two hybrids along with one standard check (GJOH-3) were evaluated in randomized block design with three replications during kharif 2016 at the college farm, Navsari Agricultural University, Navsari. The highest heterobeltiosis was observed in crosses KS-404 x GAO-5 followed by JOL-11-12 x GAO-5 and AOL-03-1 x GAO-5 and the highest standard heterosis for cross JOL-11-12 x GAO-5. High heterosis for fruit yield per plant in these hybrids was due to, positive heterotic response in other yield related characters viz., plant height, fruit yield per plant and fruit dry weight.
