Veldt grape or adamant creeper is one of the nutritionally rich plant, the potential of which as a vegetable crop is still under explored. The lack of genetic information regarding the variability parameters of this crop is a limitation for the breeding programme. Hence the present study was conducted in ten veldt grape ecotypes collected from different geographical regions and were raised in randomized block design with three replications. Nine key biometrical traits were recorded and were statistically analyzed. The analysis revealed that phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV) for all the traits. High heritability coupled with high genetic advance as percent of mean was observed for the characters viz., Vine length, number of primary branches, internodes, leaves, leaf length, width, stem weight and single plant yield. The results obtained from the genetic analysis of veldt grape in the present study can be utilized for yield improvement in the crop and mapping out suitable selection procedure for further breeding programmes.
