The experiment trial were conducted in two years with aims to determine average mean performance of sponge gourd involving 14 parental lines and their 40 F1 hybrids with three replications in RBD. Analysis of variances for line × tester mating design revealed that variance due to treatments, parents and crosses were highly significant for all the traits in both the years, variances due to parents vs. crosses were highly significant for all the characters except for vine length and fruit circumference in both the years and variances due to line vs. testers were highly significant for all the traits except for fruit circumference and average fruit weight in both the years along with some of the component traits in Y1 and Y2. Partitioning of variances into lines revealed highly significant differences for all the traits and variances due to testers were also highly significant for all the traits in both the years. The highest mean performance for fruit yield per plant (kg) along with some of the component traits was exhibited by parents NDSG-21 (3.39 and 3.51), NDSG-12 (3.36 and 3.24), NDSG-1 (3.28 and 3.13), Pusa Chikni (3.24 and 3.18) and NDSG-15 (3.04 and 2.99) in both the years and some others genotypes given better performance in respects to fruit yield and other contributing traits. Highest yielding hybrids was NDSG-55 × NDSG-11 (3.95 and 4.23 kg) followed by NDSG-63 × Pusa Chikni (3.95 and 4.35 kg) and NDSG-24 × Pusa Chikni (3.89 and 4.12 kg) in Y1 and Y2,respectively, while some other parents and also hybrids given better performance in respects to fruit yield and other contributing traits. The above mentioned genotypes may be used as donor parents in hybridization programme for developing high yielding varieties of respective groups.
