Fourteen genotypes of ridge gourd were evaluated during kharif 2006 and 2007 at Vegetable Breeding Station, Agricultural Research Institute, Rajendranagr, Hyderabad and showed that the phenotypic coefficient of variation was greater than genotypic coefficient of variation for most of the traits under study. Relatively high phenotypic and genotypic coefficients of variation were recorded for fruit length, number of fruits per vine and fruit yield. High heritability associated with hign expected genetic advance as per cent of mean was observed for fruit length, number of fruits per vine and node number at first fruit harvested which could be improved by simple selection in early generations. The results revealed that the yield was significantly and positively correlated with number of fruits per vine both at genotypic and phenotypic levels.
