Abstract: An experiment was conducted to evaluate the genetic variability present in the fourteen genotype, in which one variety is the standard check (Arka Sumeet). Observation were recorded on various yield and yield contributing traits viz., days to 1st Male Flowering, days 1st female flowering, days to 50% Flowering, node to first male flower, node to first female flower Sex Ratio, vine length cm at 90 days, days to 1st harvest, days to last harvest, fruit length, flesh thickness, rind thickness, fruit set %, fruit diameter, fruits/ Plant, average fruit weight, fruit yield/plant, fruit yield per ha. Analysis of variance showed the significant variability for all the studied characters. High values of GCV and PCV were observed for characters viz., fruit yield per plant (45.09 and 45.92), fruit yield per ha (45.10 and 45.91), fruit diameter (29.74 and 30.00), number of fruits per plant (27.42 and 28.31), average fruit weight (26.10 and 26.62), sex ratio (24.84 and 25.15), rind thickness (22.11 and 22.65), fruit length (20.01 and 20.40) and which indicates the presence of high genetic variation. Were high heritability coupled with high genetic advance observed for the traits viz, fruit yield per hectare, Fruit yield per Plant, Fruit diameter, No. Fruits per Plant, average weight, node to first female flower, sex ratio, rind thickness, fruit length, vine length cm at 90 day, flesh thickness, node to first male flower, days to taken first female flower and fruit set percent which indicates presence of additive gene action and demands for population improvement by selection.
