BGS 166, Male sterile genetic 25, msg25
Stock number: BGS 166
Locus name: Male sterile genetic 25
Locus symbol: msg25
Previous nomenclature and gene symbolization:
Male sterile = msg,,r (8).
Inheritance:
Monofactorial recessive (3, 8).
Located in chromosome 4HL (2, 7); msg25.r is near the centromere and proximal from the Blx1 (Blue aleurone xenia 1) locus (7, 10); the Bowman backcross-derived line for msg25.r, BW560, did not retain any donor parent SNP markers polymorphisms compared to Bowman (1).
Description:
Selfing - 0.7% for msg25.r (7), 2.6% for msg25.dz (4).
Outcrossing - complete female fertility (7).
Stamens - anthers smaller than fertile sib, but some have stomium. Some filament elongation may occur (7).

Origin of mutant:
A spontaneous mutant in Betzes (PI 129430) (7).
Mutational events:
msg25.r (MSS086, GSHO 744) in Betzes (PI 129430) (7); msg25.dz (MSS374) in Klages (CIho 15487) (4, 5, 6, 9).
Mutant used for description and seed stocks:
msg25.r (GSHO 744) in Betzes; msg25.r in Bowman (PI 483237)*7 (GSHO 2020, BW560, NGB 23428).
