Abstract

Present investigation was carried out at the Horticulture Research Centre, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut during summer season -2019. Analysis of variance revealed significant variability among the strains of okra for all character’s studied. Heritability estimates varied from 42.97 percentage for duration of crop to 97.07 percent for plant height. Number of primary branches showed high (>25%) GCV. Moderately high variability for GCV coupled with high estimates of heritability were observed for length of internode, number of nodes per plant, plant height, number of fruits per plant, fruit yield per plant and fruit yield (q/ha). High heritability (>60%) was obtained for plant height, number of fruits per plant, fruit yield per plant, number of nodes per plant, number of primary branches, fruit yield (q/ha), length of internode, days to first flower initiation, days to 50% flowering, and days to first fruit set. The moderate heritability (20%) was found to be highest for number of primary branches, length of internode, number of nodes per plant, plant height, number of fruits per plant and fruit yield per plant, while the moderate genetic advance (10%) was observed for fruit yield, days to first flower initiation, days to first fruit set, days to 50% flowering, days to first fruit picking, days to second fruit picking and fruit length.
