An experiment was carried out on study of genetic variability in 30 genotypes of ivy gourd at Horticulture Department of Rajasthan College of Agriculture, MPUAT, Udaipur during July to September 2017. Twelve Growth and quality characters were studied. The analysis of variance indicated that the mean sum of square due to genotypes were highly significant for all the characters suggesting the presence of good deal of variability in material studied. High magnitude of genotypic as well as phenotypic coefficient of variations were recorded for traits viz., petiole length (27.63% and 29.93%), inter nodal length (22.73% and 23.40%), leaf width (22.63% and 23.35%) and leaf width (22.52% and 23.56%) and highest heritability recorded for inter nodal length (94.30%) followed by leaf length (93.92%), leaf width (91.37%), ascorbic acid (89.48 %), petiole length (85.17%), fruit weight (82.10%), fruit length (79.98%) and chlorophyll content in leaves (78.23%).The highest genetic gain was recorded for petiole length (52.52%) followed by viz., inter nodal length (45.47%), leaf length (45.17%), leaf width (44.34%), fruit weight (34.21%),  fruit length (28.24%) fruit diameter (23.31%) & genetic advance were also higher for some characters. Availability of high GCV & PCV shows presence of sufficient genetic variability for evaluated traits. This indicates that there is an ample scope of selection in the present gene pool for yield and its components.
