Abstract:
The present investigation was carried out at the Horticulture Research Centre, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut during summer season 2021. Analysis of variance revealed significant variability among the genotypes of okra for all characters studied. The PCV were higher than the GCV for all the characters indicating important role of environment. The PCV and GCV were higher for number of primary branches per plant. While moderate PCV and GCV was seen, plant height, internodes length, number of nodes per plant, number of fruits per plant, fruit length, number of seeds per fruit, weight of 100 seed, fruit yield per plant. Whereas PCV and GCV was found low days to 50 per cent flowering, days to first flowering and fruit diameter. The highest value of broad sense of heritability was recorded for all the traits. The highest genetic advance as per cent of mean was recorded plant height, number of primary branches per plant, internodes length, number of nodes per plant, number of fruits per plant, fruit length, number of seeds per fruit, weight of 100 seed and fruit yield per plant. While moderate GAM was recorded days to 50 per cent flowering, days to first flowering fruit diameter. Number of primary branches per plant recorded high GCV and PCV, high heritability along with high genetic advance as a per cent of the mean (GAM) indicates the governance of additive gene on trait expression while high heritability and low GAM elucidated the non-additive gene action governing the trait.
