Abstract:

Correlation and path co-efficient analysis for 18 traits were conducted for thirty genotypes of ridge gourd during 2010-11 at Kittur Rani Channamma College of Horticulture, Arabhavi, Karnataka, India. The Values of genotypic correlation co-efficient were greater than the phenotypic correlation co-efficient. Fruit yield per plant was highly significant and positively correlated with vine length at 45 and 90 DAS, number of branches at 90 DAS, number of leaves at 45 and 90 DAS, node to first female and male flowering, days to last harvest, sex ratio, number of fruits per plant, fruit yield per plot, average fruit weight and fruit length at both genotypic and phenotypic level. Whereas days to first female flowering, days to 50 per cent flowering, days to first male flowering and days to first harvest were negative and highly significant correlation with fruit yield per plant. Path co-efficient analysis revealed that number of fruits per plant had the direct effect on yield, followed by average fruit weight and fruit length both at phenotypic and genotypic level. Thus, selection for these characters will improve the yield. The results indicated that number of fruits per plant and average fruit weight can be considered during selection for improved yield in ridge gourd.
