Abstract:
Twenty-seven F₁’s developed from a line x tester involving twelve parents (check variety) in bottle gourd were evaluated in randomized block design with three replications during Zaid 2019 and 2020 at the Main Experiment Station, Achayra Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya. These studies were aimed to study the extent of heterosis over better parent and standard check Pusa Naveen. Analysis of variance indicated presence of considerable variability among genotypes all the characters under study. The exploitation of heterosis requires an intensive evaluation of germplasm to find out diverse donors with high nicking of genes and further identification of heterotic crosses. The cross combination BG132 x BG 619, N. Pooja sel-1 x N. Rashmi, BG 7 x N. Rashmi and Pb round x BG 619 were showed highly positive significant heterosis over standard check for fruit yield per plant, whereas, crosses BG 38-1 x N. Rashmi, BG132 x BG 0-2 and BG 7 x BG 0-2, for node number to first male flower anthesis and BG 7 x BG 0-2, BG132 x N. Rashmi and N. Pooja sel-1 x BG 0-2 showed significant negative heterosis over standard check for earliness.
