Abstract:

Cucumber (Cucumis sativus L.) is the most preferred versatile fruit consumed in various ways, salad ingredient, pickles, deserts fruit and as a cooked vegetable, Crop improvement in cucumber has gain lot of importance compared to other cucurbit vegetables. Therefore the present investigation has been carried out to know these extend of heterosis for yield parameters and quality parameters. The experimental materials consisted of five Lines and five Testers which were collected from the germplasms maintained by the Department of Vegetable Science, College of Horticulture, UHS Campus, GKVK, and Bengaluru. Twenty five 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 number of fruits per plant, fruit diameter (cm), fruit length (cm), average fruit weight (g), fruit yield per plant (kg). shelf life (days), cavity thickness (cm), flesh thickness (cm), Rind thickness (mm), Analysis of variance was carried out s for all the characters observed and population mean for each of the replication was used for analysis. The variance due to genotypes (crosses and parents) was highly significant (at p=0.01) for all the traits studied viz number of fruits per vine, fruit length (cm), fruit diameter (cm), average fruit weight (g), fruit yield per plant(kg),shelf life (days),cavity thickness (cm), flesh thickness (cm) and rind thickness (mm). The hybrids viz Green long × Poinsette, Green long × Pusa Uday, Pondicherry 1 × Punjab Naveen were found as best for yield per vine, for fruit length, average fruit weight, number of fruits per vine over the check Chitra.
