Abstract:
The present investigation was carried out during kharif 2018-19 at Horticultural Research Station, Lam farm, Guntur to estimate the genetic variability, heritability and genetic advance for twelve quantitative traits in F₂ population of two crosses namely viz., LCA-764 x LCA-315 and MS-276A x LCA-801. The PCV was higher than GCV and the difference between PCV and GCV was narrow for most of the characters revealing little influence of the environment in the expression of these traits. High magnitude of PCV and GCV were observed for number of fruits per plant, number of seeds per fruit and dry fruit yield per plant suggesting the existence of wide range of genetic variability in the both crosses for these traits and thus the scope for improvement of these characters through simple selection would be better. High heritability coupled with high genetic advance as per cent of mean was observed for plant height, fruit diameter, number of fruits per plant and dry fruit yield per plant indicating these characters are governed by additive gene action making the simple selection more effective.
