Abstract:

An Indian origin cucumber (Cucumis sativus L.) is one of the most popular vegetables of the family Cucurbitaceae. It is the preferred in various ways, salad ingredient, pickles, deserts fruit and as a cooked vegetable, hence it has attained the crop improvement as compared to other cucurbit vegetables. Therefore the present investigation has been carried out to know the extent of heterosis for growth and yield parameters. The experimental materials consisted of 5 Lines and 5 Testers of cucumber collected from the germplasm maintained by the Department of Vegetable Science, College of Horticulture, UHS Campus, GKVK, and Bengaluru. Their 25 F1’s were developed by crossing them in Line X Tester mating design. The IIHR-285, IIHR-341, IIHR-304, Green Long, Pondicherry-1, were used as lines and the Poinsette, Phule Shubhangi, Punjab Naveen, Pusa Uday, Kerala-1 were used as testers based on their yield potentiality. Observation from five competitive plants was recorded on various characters viz., vine length (cm), number of branches per vine, number of nodes per vine, Node of female flower appearance, node of male flower appearance, days to first fruit harvest, sex ratio, days to female flower anthesis and on fruit yield per plant (kg). Analysis of variance was carried out separately for all the characters. The present experiment identified the important hybrids for commercial use viz Green long × Poinsette, Green long × Pusa Uday, Pondicherry 1 × Punjab Naveen as which have exhibited the maximum significant standard heterosis for fruit yield per vine , for fruit length, average fruit weight, number of fruits per vine over the check Chitra.
