Abstract: Thirteen parental lines and 30 F1 hybrids of bitter gourd obtained from Line × Tester mating design were studied to investigate the extent of combining ability for yield and quality characters. These parents along with their hybrids were evaluated in a randomized block design (RBD) with three replications. The analysis of variance for combining ability revealed that the mean sum of squares due to lines and testers were highly significant for almost all the characters under study except for vine length, number of primary branches per plant, fruit width and total soluble solids (TSS) content for which testers showed no significant differences. The estimated component of variance of specific combining ability (sca) was higher than general combining ability (GCA) for all the characters except fruit width indicating the predominance of non-additive gene actions for most of the characters under study. The lines IC-085612, Jaunpuri Green, IC-085611 and Katehi were found to be good general combiners for fruit yield as well as for quality parameters. These lines can be exploited in future breeding programme for improvement in bitter gourd. Among 30 cross combinations, the crosses IC-085611 × Meghna, OBGCS-1 × Katheri and Jaunpuri Green × Meghna exhibited high sca effects for various yield and its attributing traits. These crosses could be further exploited for the production of F1 hybrids.
