The study was carried out on 12 genotypes of ridge gourd to assess mean variability, heritability and genetic advance. Of the 12 genotypes, LA 12 recorded highest fruit yield/plant followed by LA 10 and LA 9. The GCV for different characters ranged from 13.36 to 33.77%. High GCV was observed for number of female flowers/plant, yield/plant, number of fruits/plant and flesh thickness. High heritability was observed for days to first female flowering, number of male flowers/plant, yield/plant, number of female flowers/plant and flesh thickness. When heritability and genetic advance as per cent over mean were considered together, number of female flowers/plant, yield/plant, number of fruits/plant and flesh thickness recorded highest values of both.
