Abstract

The current study was implemented during the kharif 2022 at Vegetable Research Farm of Rani Lakshmi Bai Central Agricultural University, Jhansi, Uttar Pradesh. The experimental material comprises 30 bottle gourd genotypes. Which were planted in three replications using a randomized block strategy in order to measure genetic progress, heritability, genetic variability and genetic diversity within the genotypes. Observation for all the parameters was recorded in three selected plants of each treatment. The experiment's analysis of variance revealed incredibly substantial variations between each of the 30 genotypes for every character and also a wide range of mean values among the genotypes for different characters under study were observed. A very high magnitude of GCV and PCV was recorded for fruit length (cm), fruit width (cm) and yield per plant (Kg). Low or insignificant difference between GCV and PCV was recorded for most of the traits indicated that the investigated traits were less impacted by environment. High heritability combined with high genetic advance was recorded for days to first flowering bud, fruit length, fruit weight, number of fruits per plant, fruit width, yield per plant, total soluble solids, protein content and ascorbic acid content. Based on (D2) statistics, thirty genotypes with comparable features were sorted into five substantially diverse clusters. Grouping of genotypes into different diverse clusters showed considerable amount of diversity among the genotypes

Conclusion

It is possible to draw the very convenient conclusion that there is a great deal of scope for improvement in the desired attributes of this seemingly highly valuable vegetable crop, which has not received the attention it deserves given its potential. This conclusion is based on data on various important economic traits, including phenotypic and genotypic coefficients of variability, heritability, genetic advance in percent of mean and genetic divergence analysis
