The present experiment was carried out at vegetable research center, G B Pant University of Agriculture and Technology, Pantnagar, Uttarakhand during the July-October, 2014 and February-June, 2015 in randomized block design with three replications to assess genetic variability, heritability and genetic advance as percent of mean for various yield and its contributing traits. data were recorded on days to first male flowers, node number to first male flower, days to first female flowers, node number to first female flower, internodal length, days to first fruit harvest, number of fruits per plant, fruit length, fruit diameter, fruit weight, test weight, seed index, primary branches per plant, plant height total fruit yield per hectare. Analysis of variance revealed significant differences among the genotypes for all the traits studied indicating the presence of sufficient variability in the studied material. | Assessment of genetic variability in cucumber (Cucumis sativus L.)
