Interpretive Summary: Nine sorghum [Sorghum bicolor (L.) Moench] A1 cyto plasmic-genic male sterile seed parent (A) and their maintainer (B) lines were released by the Kansas State University, Agricultural Research Center, Hays, Kansas in August 2014. These nine lines were developed from random mating between the selected germplasm (PI550610B, IS2692R, IS9454R, IS9335R) and different genetic male-sterile (GMS) ms3 populations like KP8B, B51-B (plant, purple; seed white; glume, black), ms3 tan, and white tan B06-41701-313 with different combinations using a recurrent selection followed by pedigree and back cross breeding methods. The lines KS133A/B to KS137A/B are early in maturity and come to flowering in 60 to 65 days whereas, the lines KS138A/B to KS141A/B are medium in maturity and come to flowering in 65 to 70 days. In general, these A/B lines are three-dwarf (dw1, Dw2, dw3, dw4) in height, photoperiod-insensitive, and possess unique combinations of plant and seed color. All nine seed parent lines are tannin free, short in peduncle length, panicles with good panicle exsertion and combining ability for yield and standability.

Technical Abstract: Nine sorghum [Sorghum bicolor (L.) Moench] A1 cyto plasmic-genic male sterile seed parent (A) and their maintainer (B) lines [KS 133A/B, KS 134A/B, KS 135A/B, KS 136A/B, KS 137A/B, KS 138A/B, KS 139A/B, KS 140A/B and KS 141A/B] were released by the Kansas State University, Agricultural Research Center, Hays, Kansas in August 2014. These nine lines were developed from random mating between the selected germplasm (PI550610B, IS2692R, IS9454R, IS9335R) and different genetic male-sterile (GMS) ms3 populations like KP8B, B51-B (plant, purple; seed white; glume, black), ms3 tan, and white tan B06-41701-313 with different combinations using a recurrent selection followed by pedigree and back cross breeding methods.
