Twenty four diverse genotypes of cucumber collected from different indigenous sources were planted in randomized complete block design, for three consecutive seasons during Rabi for the years 2016, 2017 and 2018 and were assessed on pooled analysis basis to know the nature and magnitude of variability and genetic divergence for different horticultural traits. The genotype KCS 7 gave maximum mean value for number of fruits per plant, yield per vine and yield per hectare. High phenotypic coefficient of variability (PCV), genotypic coefficient of variability (GCV) and heritability estimates coupled with high genetic gain were observed for node at which first female flower appeared, number of fruits per plant, yield per vine and yield per hectare indicated the existence of wide range of variations and offers better scope for improvement through selection. The genotypes were grouped into 7 clusters and the highest (35.48) inter cluster distance was recorded between cluster III and VII. The diverse genotypes characterized by maximum inter cluster distance will differ in phenotypic performance and therefore, selection of divergent parents should be based on these cluster distances to obtain favorable hybrids and transgressive segregants in cucumber.
