Genetic evaluation of Cucumber [Cucumis sativusL.] genotypes for some yield and related traits
Keywords: Genetic improvement, selection, cucumber, yield attributes
AbstractThirty-eight advanced lines of cucumber (Cucumis sativus L.) were evaluated for variability, heritability and genetic advance for yield and contributing traits. Genotypic coefficient of variation and phenotypic coefficient of variation were highest for node at first female flower appearance followed by node at first male flower appearance, yield per plant, seed cavity breadth, average fruit weight and number of fruits per plant. High heritability and high estimated genetic advance over mean were observed for nodes per vine (83.43), node at first female flower appearance (82.17), days to first female flower opening (83.72), days to first male flower opening (92.63), days to first harvest (83.04), number of fruits per plant (85.78), fruit length (88.92), fruit breadth (86.91), seed cavity length (85.97), seed cavity breadth (85.09), number of seeds per fruit (95.17) and 100 seed weight (93.10) thus indicating that these characters had additive gene effect and therefore, they are more reliable for effective selection.
