Fertility Restoration Of The Sorghum A3 Male-Sterile Cytoplasm Through A Sporophytic Mechanism Derived From Sudangrass, Hoang V. Tang, Jeffrey F. Pedersen, Christine D. Chase, Daryl R. Pring

Department of Agronomy and Horticulture: Faculty Publications

Fertility restoration of sorghum [Sorghum bicolor (L.) Moench] lines carrying the IS1112C (A3 group) male-sterile cytoplasm has been documented as a two-gene gametophytic mechanism involving complementary action of restoring alleles designated Rf3 and Rf4, as derived from IS1112C. Fertility restoration capability has also been reported from sudangrass (S. bicolor subsp. drummondii) populations. We describe characteristics of a fertility restoration system derived from sudangrass, in which male-sterile individuals were observed at high frequency in backcross and F₂-F₃ segregating populations. Segregation analyses were consistent with a sporophytic restoration system involving two complementary genes. Pollen iodine …
