BGS 502, Male sterile genetic 39, msg39
Stock number: BGS 502
Locus name: Male sterile genetic 39
Locus symbol: msg39
Previous nomenclature and gene symbolization:
Male sterile dm = msg,,dm (5).
Inheritance:
Monofactorial recessive (1, 5).
Located in chromosome 3HL (2); msg39.dm is associated with SNP markers from 1_0312 to 1_0044 (positions 173.82 to 190.87 cM) in 3H bin 12 of a heterozygous plant from the Bowman backcross-derived stock BW575 (2), in 3H bin 12. The msg36.dm and msg39.ff mutants were previously associated with chromosome 6H, over 33.9 cM from the rob1 (orange lemma 1) locus (3).
Description:
Selfing - about 1% in Bozeman, Montana, USA and Elimäki, Finland (1, 5).
Outcrossing - complete female fertility (1).
Stamens - anthers are the same size as fertile sibs, stomium present, and filament elongates (1, 5). Pollen shower is normal (1).
The pollen grains of the msg39.dm and msg39.dn mutants are non-functional because aperture development is abnormal. These mutants can be classified as pollen steriles (1).

Origin of mutant:
A spontaneous mutant in a Finnish six-rowed barley (P11, CIho 15836) (1, 5).
Mutational events:
msg39.dm (MSS361, GSHO 2391, GSHO 3021) in P11 (CIho 15836) (4, 7); msg39.dn (MSS362, GSHO 3022) in a Finnish six-rowed barley (H31, CIho 15837) (1, 4, 7); msg39.ff (MSS407) in Sabarlis (CIho 15484) (4, 6).
Mutant used for description and seed stocks:
msg39.dm (GSHO 2391) in P11; msg39.dm in Bowman (PI 483237)*7 (GSHO 2080, BW575, NGB 24135).
