Abstract:
The present investigation entitled “Combining ability analysis for grain yield and other associated traits in Rice (Oryza sativa L.)” was undertaken with the objective to study the combining ability from three standard CMS lines and twelve restorer as parental material. Thirty six hybrids were developed by crossing three CMS and seven restorer lines in L x T mating design for 8 quantitative characters, viz., days to 50 percent flowering, days to maturity, plant height at maturity, productive tillers per plant, tillers per square meter, Thousand grain weight, grains per panicle, yield per plant and Hybrids were evaluated in randomized block design (RBD) with three replications. Among the three testers studied, IR-58025 A was found to be the good general combiners for most of the characters studied, which indicated the usefulness of such exotic male sterile line for involving in crossing with the local restorers. Among the restorers, IR61614, HR1005, RPHR51 and RPHR612 are found to be good general combiners for quantitative characters. Specific combinations like IR-58025 A x IR66, RTN6- A x BR827-35, IR-58025 A x RPHR2, were identified as better hybrids.
