Abstract

The present investigation was undertaken during Kharif 2017-18, College of Horticulture, Mojerla, Sri Konda Laxman Telangana State Horticultural University, Telangana. The trial was laid out in Randomized Block Design with twenty seven bitter gourd genotypes. Analysis of variance revealed significant differences among all the genotypes for all the characters. The genetic parameters were studied to elucidate the genetic variability, heritability and genetic advance in bitter gourd (Momordica charantia L.). The genotypes exhibited a large range of variability for all the characters. Phenotypic coefficient of variation (PCV) was more than genotypic coefficient of variation (GCV) for all the characters studied. PCV was higher than the appropriate GCV in all aspects that describe the environmental factors that influence their expression to some degree or another. Heritability (> 60) have been observed for vine length, number of primary branches per vine, number of nodes per vine, Internodal

Keywords

Conclusion

The analysis of variance revealed significant difference for eighteen characters studied and reported that there was sufficient amount of variability exist among the genotypes. Wide range of variability was observed for vine length, number of fruits per plant, average fruit weight, fruit length, total fruit yield indicating the scope for selection of suitable initial breeding material for further improvement. High PCV and GCV estimates were recorded The difference between PCV and GCV values were minimum, indicating that the traits under study were less influenced by environment and these characters could be improved by following phenotypic selection. Heritability estimates were high for all the characters studied except days to last fruit harvest. This suggested the greater effectiveness of selection due to less influence of environment and improvement to be expected for these characters in future breeding programme as the genetic variance is mostly due to the additive gene action.
