Twenty two pointed gourd genotypes were evaluated during Kharif of 2016-17 at College of Horticulture, Dr. Y. S. R. Horticultural University, Venkataramannagudem, West Godavari district, Andhra Pradesh. The objective was to estimate the nature and magnitude of genetic variability, heritability and genetic gain for seventeen important characters. Analysis of variance revealed presence of considerable variability among the genotypes for all seventeen characters. The magnitude of PCV was higher than the corresponding GCV for all the characters studied. Among the characters studied, high PCV and GCV were observed for characters like observed fruit weight (g), pulp weight per fruit (g), pulp seed ratio, number of seeds per fruit, seed weight per fruit, internodal length and fruit yield (t/ha) indicating high variability available in the germplasm for these characters for further improvement. High heritability coupled with high genetic advance as per cent of mean was observed for characters number of nodes per vine, internodal length, node at which first female flower appeared, fruit length, fruit weight, pulp weight per fruit, pulp seed ratio, number of fruits per plant, fruit yield, number of seeds per fruit, seeds weight per fruit These confirm presence of sufficient variability in the germplasm, predominance of additive gene action and high transmissibility of the characters. Therefore, direct selection will be rewarding depending upon these traits. Hence, hybridization followed by selection will be promising for improving these traits.
