BGS 503, Male sterile genetic 40, msg40
Stock number: BGS 503
Locus name: Male sterile genetic 40
Locus symbol: msg40
Previous nomenclature and gene symbolization:
Male sterile ac = msg,,ac (5, 7).
Male sterile = ms-C (7).
Inheritance:
Monofactorial recessive (5).
Located in chromosome 6HL (1, 2); msg40.ac is over 27.8 cM from the rob1 (orange lemma 1) locus (2); msg40.ac is associated with SNP markers 2_1025 to 2_0036 (positions 147.51 to 169.88 cM) in 6H bins 09 to 11 in a heterozygous plant from Bowman backcross-derived line BW577 (1).
Description:
Selfing - none (5).
Outcrossing - less than 30% in crosses and in the Bowman backcross-derived line (3, 5).
Stamens - anthers are smaller than those of fertile sibs, no stomium or filament elongation (5).

Origin of mutant:
A spontaneous mutant in Conquest (CIho 11683) (6).
Mutational events:
msg40.ac (MSS095, GSHO 2393) in Conquest (CIho 11683) (4, 5, 7).
Mutant used for description and seed stocks:
msg40.ac (MSS095, GSHO 2393) in Conquest; msg40.ac in Bowman (PI 483237)*6 (GSHO 2081, BW577, NGB 23439).
