Abstract:

Eighteen F1s were generated from line x tester mating design using six parents as lines and three parents as testers during rabi, 2015-16. The F1s along with their parents were evaluated altogether during rabi, 2016-17 for fruit yield and component characters in a randomized block design (RBD) with three replications at the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat, Assam. The heterosis was worked out for the quantitative traits viz., days to 50 percent flowering, plant height (cm), number of branches per plant, fruit length (cm), fruit girth (cm), fruit weight (g), number of fruits per plant, number of seeds per fruit, fruit yield per plant (kg), crude fiber content (%) and shelf life (days) of fruits. The magnitudes of mid-parent heterosis (MPH), better-parent heterosis (BPH) and standard heterosis (SPH) were obtained in all the eighteen F1s for eleven characters. The study revealed that the F1 SX × SM-6-7 gave the highest estimate of SPH (40.17 %) and it was followed by the other promising F1,s viz., BM × SM-6-7 (39.19%), SX × Longai (36.61%), DH × Longai (36.12%), SX × JC-1(35.38%), MLC-1 × JC-1 (33.66%), MLC-1 × Longai (30.59%) and BM × Longai (25.80%) for fruit yield per plant.
