Abstract: The present study was carried out among forty-nine Indian mustard genotypes involving F1s, their parents and 2 checks developed through Line x Tester mating design and evaluated at Breeding Research Farm, MPUAT, Udaipur in Rabi-2018 in Randomized Block Design. Results revealed that contribution of General combining ability to total mean squares was higher than that of Specific combining ability for all the traits, providing that additive gene action was more important in their inheritance. The analysis of variance revealed that the mean squares due to genotypes, parents, crosses and parents v/s crosses were significant for all the traits. General combining ability mean squares for lines and testers and Specific combining ability mean squares were significant for most of the traits indicating that both additive and nonadditive gene action were involved in the inheritance of these traits. However, the contribution of General combining ability to total mean squares was higher than that of Specific combining ability for DOF, DOM, NSP, NPB, LMA, LS, SYP HI and OC traits, providing that additive gene action was more important, while non-additive gene action for resting traits. Lines PM-27 and SKM-1313 had positive General combining ability effects for seed yield per plant and negative General combining ability effects for oil content. These lines can be used as parents to create synthetic varieties or hybrids.
