Abstract: To assess the mean performance and extent of genetic variability, thirteen parents (10 lines and 3 testers) and their 18 hybrids (F1) along with the standard check (Pusa Sanyog) were evaluated in randomized complete block design with three replications. The observations were recorded on various quality (TSS), economically important insect pest (Incidence of fruit fly), diseases (severity of powdery and downy mildew mildew) and seed traits (seed germination, seed vigour index-I and II). The analysis of variance indicated highly significant differences among the parents, F1 (hybrids) for all the traits studied. The experimental results revealed that among parents UHF-CUC-13, UHF-CUC-11, UHF-CUC-15, UHF-CUC-8 (Lines) and Solan Srijan (Tester) while, cross-combinations viz., UHF-CUC-13 × Solan Srijan, UHF-CUC-11 × Solan Srijan, UHF-CUC-6 × K-75, UHF-CUC-15 × Solan Srijan and UHF-CUC-8 × Solan Srijan were found superior on the basis of overall mean performance for all the traits under study. Hence, these parents and cross combinations can be released as a substitute for existing varieties/hybrid of cucumber and can be used in further breeding improvement programme.
