A study was undertaken to elicit information on the identification of maintainers and restorers for their utilization in hybridization programme as the parental lines. Hybrid rice is the best practically feasible and readily acceptable options available to increase the production. For the development of viable, adoptable rice hybrids through utilization of cytoplasmic genetic male sterility, the processes of identification of maintainers and restorers involving local elite lines has become inevitable. A Total of thirty eight rice genotypes of diverse source of origin were test crossed with cytoplasmic male sterile (CMS) line IR79156A for the evaluation of the genotypes in order to identify potential restorers and maintainers. The F1’s crossed between genotypes and CMS line expressed various degree of fertility reactions. Among the tested cytoplasmic male sterile genotypes, 18 genotypes expressed restorer (R) reaction. Out of the remaining lines 17 genotypes were identified as partial restorers and 3 lines as partial maintainers.
