Abstract:
The present investigation was undertaken to generate information about the magnitude of heterobeltiosis and standard heterosis for fruit yield and its component characters in bottle gourd. The experimental material consisted of nine female parents, four male parents and their resultant 36 hybrids developed by using line × tester mating design and one standard check GABGH-1. The experiment was laid out in randomized block design with three replications at the Main Vegetable Research Station Farm, Anand Agricultural University, Anand during Kharif, 2021. Among the 36 hybrids developed, eight hybrids showed significantly positive heterosis over better parent and 10 hybrids showed significant positive heterosis over standard check GABGH-1 for fruit yield. As per better parent heterosis, the best performing positively significant hybrids for fruit yield per vine were ABGS 11-18 × Arka Bahar, ABGS 11-24 × Arka Bahar and ABGS 11-23 × ABG 1 and for standard heterosis, the best performing positively significant hybrids for fruit yield per vine were ABGS 11-22 × Punjab Komal, ABGS 11-23 × ABG 1 and ABGS 11-17 × ABG 1. These cross combinations can be further exploited in breeding programmes in bottle gourd.
