Abstract
The studies on heterosis in bhendi was conducted with 20 F1’s developed from 9 parents viz., SKY/DR/RS/107 (L1), 3 (L2), IC 69257 (L3), 307-10-1-II (L4), 608-8-1 (T1), 770 (T2), IC 140880 (T3), 137-10-1,2 (T4) and Tiruchi Local (T5) in a Line x Tester mating design. The hybrids along with parents were evaluated in RBD with three replications. The hybrid L2 x T3 was considered the best as it has recorded higher magnitude of heterobeltiosis for plant height at flowering (17.49 per cent), plant height at final harvest (42.95 per cent), leaf area index (64.21 per cent), stem diameter (82.79 per cent), fruit length (22.98 per cent), fruit girth (6.17 per cent), number of fruits plant-1 (42.70 per cent) and yield plant-1 (57.77 per cent). The maximum heterotic vigour was found in L2 x T2 for fruit weight (47.24 per cent) and number of fruits plant-1 (96.67 per cent).
