Abstract
Markers tightly associated with a sorghum (Sorghum bicolor) cms fertility restorer gene are identified, as well as genes containing the pentatrico peptide repeat (PPR) motif. Methods for marker assisted selection of restorer and non-restorer sorghum lines are provided. The markers can be used to facilitate development of the maintainer, restorer and cms sorghum lines used to make hybrids.
Claims2
A method of identifying a sorghum restorer plant by identifying an allele associated with a restorer gene, the method comprising:
- (a) detecting at least one nucleic acid from the sorghum, wherein the nucleic acid localizes to a chromosome interval flanked on each side by the marker pair of TS304T and TS050 as set out in SEQ ID NO:
- 5 and SEQ ID NO:
- 6 respectively;
- and
- (b) identifying the sorghum comprising the nucleic acid, thereby identifying the sorghum restorer plant.
