Abstract:
General combine ability and specific combine abilities were estimated in eighteen inbred lines and fort- five hybrids of bottle gourd [Lagenaria siceraria (Mol.) Standl.]. Results indicate significant variabilities in the sixty-three genotypes population (parents and hybrids). The investigation was undertaken with eighteen varieties of bottle gourd using Line x Tester mating design at the Horticultural Research Centre, College of Horticulture, Sardar Vallabhbhai Patel University of Agriculture & Technology, Modipuram, Meerut (250110) Uttar Pradesh, in Randomized Complete Block design (RBD) with three replications, was carried out during summer, seasons 2020 and 2021. The analysis of variance for combining ability mean square due to line x tester were highly significant for days to first flower initiation, days to 50% flowering, and the lines for days to first flower initiation, days to 50% flowering, Whereas the tester for days to first flower initiation, days to 50% flowering. The genotypes IC- 394736, IC-385816, Narendra Rashmi, and Pusa Naveen exhibited significant GCA effects out of twelve characters with respect to yield (q/h) in bottle gourd. On basis of the specific combining ability effect of different crosses IC-394736 x Pusa Naveen, IC-310188 x Narendra Rashmi, Vallabh Saral x Narendra Madhuri, and IC-336820 x Narendra Madhuri were found maximum SCA effect. All these crosses promise for improvement of respective component characters in specific environments and ultimately fruit yield. These cross combinations can be utilized for the further breeding programme for crop improvement in bottle gourd.
