Three cytoplasmic genetic male sterile (cm) lines, mainly IR 58025 A, PMS 8 A and PMS 10 A were crossed with eight indigenous rice genotypes of saline alkaline and scented high yielding to identify their prospective restorers, partial restorers and effective maintainers. Study of F1S enabled to identify fourteen restorers ten partial restorers to CMS lines. None of the lines were found to be partial maintainers and effective maintainers for the CMS lines.
