An experiment was carried out to analyze genetic variability analysis for yield and its contributing traits in 69 bottle gourd genotypes during kharif season of 2015. The experiment was conducted using a randomized complete block design with three replications. The genetic parameters between yield and yield contributing characters of different bottle gourd genotypes were studied. Analysis of variance showed significant variation among the genotypes for all tested characters.

The highest fruit yield was recorded in genotype IBG 61 (433.33) which was followed by IBG 67 (351.85 q/ha), IBG 11 (287.11 q/ha number of branches per plant showed the highest genotypic and phenotypic coefficient of variations (38.45 and 39.05), whereas duration of crop showed the lowest ones (2.98 and 3.73). The highest heritability was recorded for the characters days to 50% flowering, node number of first female flower, node number of first male flower, number of branches per plant, days to first female appears, days to fruit set, 100 seed weight, days to first fruit harvest, fruit yield per plot, days to first male flower appears, fruit length, fruit girth.
