BGN  45:162 Export to PDF
Stock number: BGS 383
Locus name: Male sterile genetic 22
Locus symbol: msg22

Previous nomenclature and gene symbolization:

Male sterile e = msg,,e (5, 6).
Male sterile 22 = ms22 (2, 5).

Inheritance:

Monofactorial recessive (5).
Located in chromosome 7H (5)); msg22.e 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 homozygous male sterile plant from Bowman backcross-derived line BW557 (1).

Description:

Selfing - none (5).
Outcrossing - complete female fertility (5).
Stamens - anthers smaller than fertile sibs, no stomium or filament elongation (3).
No images

Origin of mutant:

A spontaneous mutant in a selection from Glacier/Compana (CIho 10861) (6).

Mutational events:

msg22.e (MSS073, GSHO 741, GSHO 2374) in a selection from Glacier/Compana (CIho 10861) (6, 7); msg22.fc (MSS404) in Proctor (PI 280420), msg22.fo (MSS416) in Zephyr (PI 339815) (3, 4).

Mutant used for description and seed stocks:

msg22.e (GSHO 741, GSHO 2374) in a selection from Glacier/Compana; msg22.e in Bowman (PI 483237)*7 (GSHO 1857, BW557, NGB 24131).
