Online published on 26 December, 2017. Abstract The present investigation detected unique genotypes of ridge gourd for development of high yielding hybrids in respect of general and specific combining ability with heterosis over better parent as well as economic parent. With the aim of recognizing both the phenomenon, 10 quantitative characters for yield and its component traits was examined in 28 hybrids derived from a8 × 8 diallel mating design excluding reciprocals. The best three parents identified as promising general combiner were PRG 117, PRG 131 and PRG 132 for earliness, vegetative and yield characters. For earliness, vegetative and fruit characters, number of fruits per plant, fruit yield per plant and total fruit yield the crosses like PRG 131 × PRG 132, PCPGR 7256 × PRG117, PRG117× PRG 7 and PRG 132× PRG120 werebest specific combiners. Regarding fruiting traits PRG 131 × PRG 120, PRG 131 × PRG 132 and PRG 132 × PRG 120 showed highest heterobeltiosis and standard heterosis. For fruit yield the crosses PRG 131 × PRG 132 showed the highest heterobeltiosis and standard heterosis followed by PRG 132 × PRG 7 and PRG 131 × PRG 137 respectively.
