Other claims from this paper (9)
- Association Double-dose Rfo2 on chromosome 1B restores selfed seed fertility above 25%.
- Association With one dose of Rfo2, a double-dose chromosome 7A factor is needed for fertility restoration above 25%.
- Association With one dose of Rfo2, a double-dose factor on chromosome 5A or 5B is needed for fertility restoration above 25%.
- Association Absence of Rfo2 causes complete sterility.
- Association Chromosome 1A contains modifiers that improve fertility restoration.
- Association Chromosome 4A contains modifiers that improve fertility restoration.
- Association Chromosome 7D contains modifiers that improve fertility restoration.
- Association A single Rfo2 dose cannot restore fertility above 25% when other restoration genes are heterozygous.
- Observation The findings provide another example of linkage between a fertility-restoring gene and a nucleolus-organizing region.
