Abstract:
Combining ability analysis was carried out in Indian mustard by crossing 6 lines and 3 testers in line x tester mating design. The parents, crosses and checks were grown in randomized block design replicated trice and observations were taken on days to 50% flowering, days to maturity, plant height, number of branches plant^-1, point to first siliqua, siliqua length, number of seeds siliqua^-1, number of siliquae plant^-1, siliquae density on main branch, 1000 seed weight, seed yield plant^-1, oil content and powdery mildew incidence. The predictability ratio was found less than unity for all characters indicated the predominant role of non-additive gene action in the expression of characters. Line Bio-902 and tester Chhattisgarh Sarson were recorded as good general combiners for seed yield and it’s contributing characters. The crosses ACN-9 × PC-6, TAM 108-1 × Chhattisgarh Sarson, and Bio-902 × Chhattisgarh Sarson showed significant negative SCA effect for seed yield and most of its contributing characters. These crosses can be forwarded to next generation to develop as a variety.
