BGS 384, Male sterile genetic 23, msg23
Stock number: BGS 384
Locus name: Male sterile genetic 23
Locus symbol: msg23
Previous nomenclature and gene symbolization:
Male sterile b = msg,,b (4, 5).
Male sterile 23 = ms23 (2, 4).
Inheritance:
Monofactorial recessive (4).
Located in chromosome 5H (1); msg23.b is associated with SNP markers 1_1198 to 2_1275 (positions 73.70 to 104.73 cM) in 5H bins 04 to 06 in a heterozygous plant from Bowman backcross-derived line BW558 (1). The msg23.b gene was previously associated with chromosome 7HL (4).
Description:
Selfing - none in msg23.b and msg23.bg (4), but 1.9 to 13.6% in msg23.y (3).
Outcrossing - complete female fertility (4).
Stamens - anthers smaller than fertile sibs, no stomium or filament elongation (4).

Origin of mutant:
A spontaneous mutant in Betzes (PI 129430) (5).
Mutational events:
msg23.b (MSS071, GSHO 2375) in Betzes (PI 129430) (5, 6); msg23.y (MSS092) in Betzes (3, 4, 6); msg23.bg (MSS321) in Betzes (2, 3, 6).
Mutant used for description and seed stocks:
