Two sorghum maternal haploid inducer lines SMHI01 and SMHI02 are provided including seed, plants and plant parts thereof. Methods for producing sorghum haploid embryos using SMHI01 and SMHI02 are also provided. The sorghum haploid embryos produced as a result of the use of either maternal haploid inducer line SMHI01 or SMHI02 may be doubled to produce doubled haploid embryos, seeds, and plants as part of a sorghum breeding program.

Sorghum maternal haploid inducing line SMHI02

Twomaternal haploid inducer lines SMHI01 and SMHI02 are provided including seed, plants and plant parts thereof. Methods for producinghaploid embryos using SMHI01 and SMHI02 are also provided. Thehaploid embryos produced as a result of the use of either maternal haploid inducer line SMHI01 or SMHI02 may be doubled to produce doubled haploid embryos, seeds, and plants as part of abreeding program.

Markers tightly associated with a() 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-restorerlines are provided. The markers can be used to facilitate development of the maintainer, restorer and cmslines used to make hybrids.
