Abstract:
The experiment comprised the study of inbreeding depression for yield attributes and yield of okra. The experimental material consisting parents were comprised ten diverse genotypes of okra namely, Arka Abhay, Parbhani Kranti, VRO-3, Sel-4, Pusa-A4, Pusa Makhmali, SB -8, IC- 282272, IC-43733 and IC-43750 obtained by way of diallel mating system without reciprocals along with check Arka Anamika. Material was evaluated during summer season of 2019 in a randomized block design with randomization of generation replicated thrice. The characters studied were plant height (cm), number of branches per plant, node at which first flower appear, number of nodes on main stem, intermodal length (cm), days to first flower, days to 50 per cent flowering, fruit length (cm), fruit width (cm), fruit weight (g), number of ridges on fruit, number of fruits per plant, days to edible fruit maturity, fruit yield per plant (g), fruit yield per ha (q), number of seeds per fruit, seed yield per plant (g), crude fiber content (%) and iodine content (mg/ 100 g). Inbreeding depression showed significantly positive values for plant height, node at which first flower appears, number of nodes on main stem, intermodal length, days to 50 per cent flowering, fruit length, fruit weight, days to edible maturity, fruit yield per hectare, number of seeds per fruit, seed yield per plant, crude fiber content and iodine. However rest of the characters showed negative values of imbreeding depression.
