An experiment was carried out to analyze genetic variability for yield and its contributing characters in 35 bottle gourd genotypes in randomized block design with three replications to assess the nature and magnitude of association among yield and its contributing traits in bottle gourd (Lagenaria siceraria). Results indicated that PCV and GCV were high (more than 20%), sex ratio for PCV was 34.19 % and GCV registered as 24.79 per cent, respectively. Moderate PCV (14.28,16.10) and GCV

... .43) were recorded for vine length and primary branches, respectively. The high genetic advance as per cent of mean along with high heritability was obtained for vine length (0.93%), fruit length (0.87%), fruit width (0.76%), primary branches (0.69%), fruits per vine (0.59 %), sex ratio (0.52%), fruit yield (0.44%), days to first female flower anthesis (0.42%), node at first female flower appears (0.41%), days to first harvest (0.40%), fruit thickness (0.37%), days to first male flower anthesis (0.37%), fruit weight (0.35%) and node at first male flower appears (0.20%).
