To study the performance of different bottle gourd under Karaikal condition, the evaluation was carried out with twenty four genotypes obtained from diverse sources. The research was aimed to study the variances, heritability, and genetic advance for nineteen characters. High estimates of genetic coefficient of variation for vine length, number of primary branches, node number at first male flower appears, fruit length, fruit width, fruit cavity, fruit flesh thickness, fruit weight, number of pickings, number of seeds per fruit, weight of 100 seeds and yield per vine indicate that themajor part of variability was due to genetic constitution. This indicates maximum amount of variability is nature, can be used in further crop improvement programme. Heritability in general was high for all the characters except days to first female flower anthesis. High heritability also indicated that there was more number of additive factors for these characters. In this experiment all the characters exhibited higher values of genetic advance as per cent of mean except node number at first female flower appears, days to first male flower anthesis, days to first female flower anthesis and days to first harvest.
