Abstract:
The present study was undertaken on cucumber in a Line x tester was undertaken with the study of combining ability variances and their effect. The 36 F1 hybrid along with their twelve line and three testers were crossed in line x tester fashion to obtained 36 F1 and evaluated in randomized block design in three replications having each experimental unit of single row with spacing of 2.5 m x 0.5 m at Vegetable Research Farm, Kalyanpur, C. S. Azad University of Agriculture and Technology, Kanpur during zaid and summer - 2018-19.The selected parental lines are consisted 12 lines (K-100, K-512, K- 40, K-1, 5- URC-11-1, Panjab Naveen, Pusa Barkha, Poinsett-76, Pahari Barsati, Poinsett, Swarn Ageti, Pusa Uday with 3 testers (PCUC-8, Swarna Poona and Boro Patana). Observations were recorded on all the six plants maintained for 20 metric traits viz. day to first male flower initiation day to first female flower initiation, number of node for first male flower, number of node for first female flower, number of branches per plant, vine of length at 60DAS, number of fruit per plant, day to first fruit set, number of fruit per vine at 60 DAS, length of fruit (cm.), number of node/wine, duration of crop average weight of fruit diameter of fruit, fruit yield (kg.)/plant, day to first fruit picking, T.S.S, specific gravity of fruit, dry matter (%).. High magnitudes of phenotypic as well as genotypic coefficients of variation were observed in case of Number of branches per plant, Average weight of fruit (kg.), Number of fruit per plant, Length of fruit (cm.), Vine of length at 60DAS. The estimates of high heritability observed in narrow sense days to first female flower initiation followed by Average weight of fruit (kg.) and Number of node for Ist female flower in E1, E2 and pooled, Genetic advance in per cent of mean was maximum for Number of branches per plant (59.69%) followed by number of fruits per plant (44.88%), Length of fruit (43.13%), in E1, E2 and pooled.
