摘要

Thirty one genotypes were screened for the restoration ability of two cytoplasmic genie male sterile (CMS) lines derived from 'WA' source (V/20A and IR 62829A) and another CMS line derived from Assam rice collection (ARC, IR 54755A). Four genotypes could restore the fertility of both the CMS lines from 'WA' soruce4 while 15 genotypes were identified as the effective maintainers. The frequency of maintainers was much higher as compared to that of restorers. For the CMS line from ARC cytosterile source, only one genotype could restore the fertility satisfactorily. IR72 was an effective restorer for the CMS lines from both the resources. Some of the genotypes behaved differently with different CMS lines of the same source.
