BGS 395, Male sterile genetic 26, msg26

BGN  45:166
Stock number: BGS 395
Locus name: Male sterile genetic 26
Locus symbol: msg26

Previous nomenclature and gene symbolization:

Male sterile u = msg,,u (7).


Monofactorial recessive (5, 6).
Located in chromosome 7HS (3, 4); msg26.u is linked to the nud1 (naked caryopsis 1) locus (3); msg26.u is linked to the ant1 (anthocyanin-less 1) locus based on linkage drag (4); msg26.u is associated with SNP markers 2_0790 to 1_1098 (positions 73.69 to 93.97 cM) in 7H bins 05 to 06 of Bowman backcross-derived line BW561 (1).


Selfing - none (6).
Outcrossing - complete female fertility (6).
Stamens - anthers smaller than fertile sibs, no stomium or filament elongation (6).
The Bowman backcross-derived line for msg26.u, BW561, has adequate self-fertility so that it can be maintained as an inbred line (2).

Origin of mutant:

A spontaneous mutant in Unitan (CIho 10421) (7).

Mutational events:

msg26.u (MSS088, GSHO 745, GSHO 2378) in Unitan (CIho 10421) (5, 7, 8).

Mutant used for description and seed stocks:

msg26.u (GSHO 745, GSHO 2378) in Unitan; msg26.u in Bowman (PI 483237)*6 (GSHO 1858, BW561, NGB 23429).
