Abstract: Investigation was carried out insponge gourd [Luffa cylindrica (L.) Roem.]to develop potentialF₁ hybrids with earliness, quality and quantity parameters. Nine diverse parents were crossed in a half diallel fashion (excluding reciprocals) for generating the 36 F₁ hybrids. All the nine parents, 36 hybrids and one standard check were evaluated in a randomized block design with three replications for various quantitative and qualitative traits. Maximum standard heterosis fordays to first female flower appearance in Kulgod local × Pusa Chikni (-14.42 %), for node at which first female flower appeared in Kulgod local × Pusa Chikni(-80.56 %),for days to first harvest in Kulgod local × KRCCH-1 (-8.21%), for days to last harvest in Kulgod local × Pusa Chikni (11.01 %), for fruiting period in Kulgod local × Pusa Chikni (26.20 %),for fruit yield per plant in Kulgod local × Pusa Chikni (100.74 %), for number of seeds per fruit in SG-6 × KRCCH-1(-42.66 %), for rind thickness in SG-3 × Pusa Chikni (36.70 %), for flesh thickness in Kulgod local × KRCCH-1 (1.45 %), for total soluble solids in Kulgod local × SG-3(12.82 %) and for physiological loss of weight in SG-4 × KRCCH-1 (-56.25 %).
