BGS 376, Male sterile genetic 21, msg21
Stock number: BGS 376
Locus name: Male sterile genetic 21
Locus symbol: msg21
Previous nomenclature and gene symbolization:
Male sterile q = msg,,q (3, 4, 6).
Male sterile 21 = ms 21 (3).
Inheritance:
Monofactorial recessive (3).
Located in chromosome 1HL (1); msg21.q is associated with SNP markers 2_0290 to 2_0780 (positions 102.33 to 154.89 cM) in 1HL bins 11 to 12 of the Bowman backcross-derived line BW556 (1).
Description:
Selfing - 3.8% at Bozeman, Montana and 2.9% at Tucson, Arizona, USA (3, 4).
Outcrossing - complete female fertility (3).
Stamens - anthers almost equal in size to fertile sibs (3). The Bowman backcross-derived line msg21.q, BW556, had 70 to 85% more selfed seed set and partially male fertile segregates were difficult to identify during backcrossing (2).

Origin of mutant:
A spontaneous mutant in a Midwest Bulk (CIho 13640) (4).
Mutational events:
msg21.q (MSS085, GSHO 2373) in CIho 13640 (CIho 13640) (3, 5).
Mutant used for description and seed stocks:
msg21.q (GSHO 2373) in CIho 13640; msg21.q in Bowman (PI 483237)*7 (GSHO 2302, BW556, NGB 23425). (The BW556 seed stock is maintained as homozygous for the msg21.q allele).
