BGS 502, Male sterile genetic 39, msg39

BGN  45:188
Stock number: BGS 502
Locus name: Male sterile genetic 39
Locus symbol: msg39

Previous nomenclature and gene symbolization:

Male sterile dm = msg,,dm (5).


Monofactorial recessive (1, 5).
Located in chromosome 3HL (2); 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 and msg39.ff mutants were previously associated with chromosome 6H, over 33.9 cM from the rob1 (orange lemma 1) locus (3).


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 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: (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: (GSHO 2391) in P11; in Bowman (PI 483237)*7 (GSHO 2080, BW575, NGB 24135).
