Abstract

Abstract : Nine sorghum [ Sorghum bicolor (L.) Moench] A1 cytoplasmic male sterile seed parent (A) and their maintainer (B) lines (KS133A [Reg. No. PL‐289, PI 674016], KS133B [Reg. No. PL‐290, PI 674017], KS134A [Reg. No. PL‐291, PI 674018], KS134B [Reg. No. PL‐292, PI 674019], KS135A [Reg. No. PL‐293, PI 674020], KS135B [Reg. No. PL‐294, PI 674021], KS136A [Reg. No. PL‐295, PI 674022], KS136B [Reg. No. PL‐296, PI 674023], KS137A [Reg. No. PL‐297, PI 674024], KS137B [Reg. No. PL‐298, PI 674025], KS138A [Reg. No. PL‐299, PI 674026], KS138B [Reg. No. PL‐300, PI 674027], KS139A [Reg. No. PL‐301, PI 674028], KS139B [Reg. No. PL‐302, PI 674029], KS140A [Reg. No. PL‐303, PI 674030], KS140B [Reg. No. PL‐304, PI 674031], KS141A [Reg. No. PL‐305, PI 674032], and KS141B [Reg. No. PL‐306, PI 674033]) were released by the Kansas State University, Agricultural Research Center, Hays, KS, 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 including 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 backcross breeding methods. The lines KS133A/B to KS137A/B are early in maturity and come to flowering in 60 to 65 d, whereas the lines KS138A/B to KS141A/B are medium in maturity and come to flowering in 65 to 70 d. In general, these A/B lines are three‐dwarf ( dw1, Dw2, dw3, dw4 ) in height, are photoperiod‐insensitive, and possess unique combinations of plant and seed color. All nine seed parent lines are tannin free, short in peduncle length, have panicles with good panicle exsertion, and have combining ability for yield and standability.
