Abstract: The present studies entitled “Genetic studies on yield and quality traits in cucumber (Cucumis sativus L.)” were carried out at the Experimental Research Farm of the Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during the years 2011 and 2012. The experimental material for the present study comprised of F 1 population of forty eight crosses, developed by crossing 16 lines and 3 testers. All the parents (16 lines and 3 testers) and their hybrids (48) along with the standard checks (KH-1 and Pusa Sanyog) were planted in a Randomized Complete Block Design for their comparative evaluation. The observations wererecorded on days to first female flower appearance, node number bearing first female flower, days to marketable maturity, fruit length (cm), fruit breadth (cm), average fruit weight (g), fruit colour, number of marketable fruits per plant, harvest duration (days), marketable yield per plot (kg) & per hectare (q), total soluble solids ( o B), cucurbitacin content (µg/100g), incidence of fruit fly (%), severity of powdery mildew (%), downy mildew (%) and angular leaf spot (%), seed germination (%) and seed vigour index-I and II. The analysis of variance indicated highly significant differences among the genotypes for all the traits studied. Experimental results revealed that five lines viz.,LC-1-1, CGN-20953, LC-2-2, CGN-19533 and Gyne-5 and two testers viz., K-75 and Poinsette were found superior on the basisof mean performance and general combining ability studies. Five cross combination viz., LC-1-1 x K-75, LC-2-2 x Poinsette, CGN-19533 x K-75, Gyne-5 x K-75 and CGN-20953 x Poinsette were found best on the basis of mean performance, specific combining ability and heterosis studies. Hence, these hybrid combinations can be tested further at multilocations before releasing as a substitute of already exiting hybrid varieties of cucumber in Himachal Pradesh and in India as well.
