Abstract:

The present investigation was carried out at Horticultural Research Station, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal, India during spring summer seasons of 2015, 2016 and 2017 in a Randomized Block Design with three replications. The morphological characterization was done as per minimal descriptors of NBPGR developed for bottle gourd. The results revealed that the greatest diversity was observed in fruit characters especially fruit shape and fruit colour among the genotypes for various characters studied. Analysis of variance revealed significant differences among genotypes for all the characters. In general PCV was marginally higher than the corresponding GCV indicated the less influence of environment in the expression of the characters under study. High heritability coupled with high genetic advance as percentage of mean was observed for vine length, number of primary branches, days to first male flower appearance, days to first female flower appearance, days to first harvest, number of fruits per plant, average fruit weight, fruit length, fruit width, fruit yield per plant, sex ratio, seed number per fruit, 100 seed weight, TSS of the pulp, total sugar content and ascorbic acid content of the pulp indicated that these characters were mainly controlled by additive gene effects and thus selection may be effective.


Keywords: Qualitative traits, Quantitative traits, Variability, Heritability and Genetic advance.
