Abstract: The present investigation entitled “Heterosis and Combining ability in cucumber (Cucumis sativus. L.)†was conducted during Kharif, 2013 to Summer 2014 under naturally ventilated polyhouse at the College of Horticulture and Forestry, Jhalawar. The material comprising of 7 parental lines, 42 F1s and one check variety were evaluated in a Randomized Block Design with three replications. The observations were recorded for fifteen characters viz., days to germination, days to fruit maturity from anthesis, days to anthesis of first male flower, days to anthesis of first female flower, node at which first male flower appeared, node at which first female flower appeared, fruit length (cm), fruit diameter (cm), fruit weight (g), days to fruit harvesting, yield per plant (kg), number of branches per plant, vine length at 30 DAS and final harvesting stage (cm) and total soluble solids. The data were subjected to analysis of variance, heterosis over mid parent, better parent and check variety and effects (Griffing, 1956, Model 1 Method 1) for each characters. Cross combination Hilton x Swarna Sheetal was the best cross as it manifested 28.78 percent, 17.87 percent and 15.99 percent heterosis over mid, better and standard parent. Heterosis for yield per plant ranged from -36.10 percent to 25.78 percent over mid parent -41.26 percent to 17.87 percent over better parent and -39.74 percent to 15.99 percent over standard parent. The analysis of variance for experimental design revealed the existence of adequate genetic variability in the experimental material for all the traits under study.
