Evaluation of rice genotypes for fertility restoration against cytoplasmic male sterility

Cytoplasmic male sterile (CMS) line IR58025A having wild abortive (WA) was crossed with 25 genotypes to assess their maintainer and restorer behavior. Most of the genotypes expressed differential fertility reactions. Among the genotypes tested, ‘VDN-2-3-1-1 ’, ‘VDN-14-2-4-1-1-1 ’, SYE-2001, ‘PKV Ganesh'and ‘VDN-3-4-1-2 ’can be considered as potential restorers for the CMS line IR58025A, as their respective hybrids showed more than 80% pollen fertility and more than 75% spikelet fertility. Rice varieties, Phule Radha and RTN24 produced sterile hybrids. The effective restorers may be used to develop hybrids, while new CMS lines may be established in locally adapted cultivars, producing sterile hybrids.
