Abstract:
The present investigation was carried out to investigate the magnitude of heterosis in 21 F₁ hybrids of Ridge gourd for earliness, growth, yield attributing and quality traits during 2021-22. These 21 hybrids are obtained by crossing seven diverse lines in diallel mating design excluding reciprocal. The best heterotic cross for fruit yield per plant was GLC-1 × GLC-3. The high magnitude of heterosis observed in this hybrid for fruit yield can be attributed to significant standard heterosis and heterobeltiosis in desirable direction for yield attributing traits viz., vine length, fruit weight and fruits per plant. This cross also exhibited significant heterosis for days to first female flower, days to marketable maturity, 100 seed weight and crude fibre. The second-best hybrid GLC-1 × GLC-6 for fruit yield per plant also showed significant heterosis in the desirable direction for fruit weight, fruits per plant, Days to marketable maturity and crude fibre.
