Identification of potential maintainers and restorers using cytoplasmic male sterile lines in rice
Eight CMS lines were crossed as lines with 31 genotypes as ‘testers’ to get 248 hybrids. The 248 hybrids were subjected topollen and spikelet fertility analysis. Among the 248 hybrids 168 hybrids were expressed as restorers 52 as PR, 28 asmaintainers. Ten tester’s viz., IR 62037, IR 72865, IR 68427,...

| Summary: | Eight CMS lines were crossed as lines with 31 genotypes as ‘testers’ to get 248 hybrids. The 248 hybrids were subjected topollen and spikelet fertility analysis. Among the 248 hybrids 168 hybrids were expressed as restorers 52 as PR, 28 asmaintainers. Ten tester’s viz., IR 62037, IR 72865, IR 68427, MDU5, TP1021, RR363-1, RR 347-1, RR 286-1, ACK 99017and ASD06-08 were identified as restorers for all the eight CMS lines. |
