Abstract: The present investigation was carried out at Vegetable Research Centre of Bihar Agricultural University, Sabour, Bhagalpur, India during Kharif seasons of 2014 in a Randomized Block Design with three replications to explore the variability among the genotypes. Fifteen parameters viz, days to first flowering, number of nodes at first harvest, inter nodal length at first harvest, vine length at first harvest, days to first harvest, fruit length, fruit diameter, number of seeds per fruit, seed weight per fruit, pulp weight per fruit, pulp: seed ratio, average fruit weight, number of fruits per plant, weight of fruit per plant and yield of fruit per hectare were taken under consideration to diagnose the variability. 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 yield of fruit, number of fruits per plant, pulp weight per fruit, number of seeds per fruit, inter nodal length at first harvest and average fruit weight indicated that these characters were mainly controlled by additive gene effects and thus selection may be rewarding for the further improvement.
