Correlation and path coefficient analysis studies in F3, F4 and F5 generations of okra (Abelmoschus esculentus L.) cross VRO-3 x 440-10-1

Abstract

The present experiment was conducted on study of correlation and path coefficient analysis in okra (Abelmoschus esculentus) cross VRO-3 x 440-10-1 was carried out with F3, F4 and F5 generations during in Summer, 2021-22, Kharif, 2022-23 and Rabi-2022-23 at Horticultural Research Station, Lam, Guntur, Andhra Pradesh. From correlation coefficient studies, it was observed from that fruit yield per plant registered positive significant correlation plant height (0.96), number of fruits per plant (0.97), fruit weight (0.97) and number of seeds per fruit (0.99) in F3 generation, Similarly in F4 generation the traits plant height (0.96), number of fruits per plant (0.76), fruit length (0.88), fruit weight (0.98) and number of seeds per fruit (0.97) respectively in F5 generation, the traits plant height (0.98), number of fruits per plant (0.97), Fruit weight (0.97) and number of seeds per fruit (0.97) were recorded. The results of path coefficient analysis showed that the following characters had positive direct effect on plant height, intermodal length and days to first flowering, fruit girth and number of seeds per fruit in F3 generation. In F4 generation the traits plant height, days to first flowering, days to last picking, fruit weight and shelf-life of fruits respectively in F5 generation the traits plant height, days to last picking, number of seeds per fruit, test weight of seeds and fibre content of fruits were recorded positive direct effect with fruit yield per plant.
