BGS 465, Male sterile genetic 28, msg28
Stock number: BGS 465
Locus name: Male sterile genetic 28
Locus symbol: msg28
Previous nomenclature and gene symbolization:
Male sterile as = msg,,as (3).
Inheritance:
Monofactorial recessive (3, 6).
Located in chromosome 2HS (1); msg28.as is associated with SNP markers 2_1015 to 2_0864 (positions 48.68 to 55.52 cM) in 2HS bin 05 of a plant presumed to be a heterozygous plant from the Bowman backcross-derived line BW563 (1). The msg28.as was previously mapped in chromosome 6 near the rob1 (orange lemma 1) locus (2).
Description:
Selfing - none (3).
Outcrossing - complete female fertility (3, 6).
Stamens - anthers rudimentary, with no stomium or filament elongation (6).
Pollen - non-staining, shrunken, and no normal-appearing grains (6).
Cytology - normal meiosis (6).

Origin of mutant:
A spontaneous mutant in York (CIho 10075) (6).
Mutational events:
msg28.as (MSS311, GSHO 2380) in York (CIho 10075) (4, 5, 6).
Mutant used for description and seed stocks:
msg28.as (GSHO 2380) in York; msg28.as in Bowman (PI 483237)*7 (GSHO 2079, BW563, NGB 24132).
