Abstract: Thirty diverse genotypes of cucumber collected from different indigenous sources were planted in randomized complete block design and were assessed to know the nature and magnitude of variability for different horticultural traits. The analysis of variance indicated significantly higher amount of variability among the genotypes for all the characters studied. High magnitude of GCV and PCV (>20 per cent) were observed for node at first female flower appear, total number of fruits per vine, fruit length, flesh thickness, average fruit weight, fruit yield per vine, fruit yield per hectare, chlorophyll content and rind thickness. High heritability coupled with high genetic advance as per cent over mean was recorded for the characters viz., field emergence, vine length, number of nodes per vine, node at first male flower appear, days to first male flowering, node at first female flower appear, days to first female flowering, total number of fruits per vine, fruit diameter, fruit length, flesh thickness, average fruit weight, yield per vine, yield per hectare, chlorophyll content and rind thickness. The study indicated that the characters with high GCV, PCV, heritability and genetic advance can be considered for direct selection for improvement in cucumber genotypes.
