BGS 373, Male sterile genetic 18, msg18

BGN  45:153 Export to PDF
Stock number: BGS 373
Locus name: Male sterile genetic 18
Locus symbol: msg18

Previous nomenclature and gene symbolization:

Male sterile 18 = ms18 (5).

Inheritance:

Monofactorial recessive (5).
Located in chromosome 5HL (2); msg18.cq is over 37.0 cM distal from the T2-7a translocation breakpoint (7); the plant of the Bowman backcross-derived line for msg18.cq stock, BW552, evaluated for SNP markers did not have any deviant markers in 5H from those of Bowman (1).

Description:

Selfing - none (5).
Outcrossing - complete female fertility (5).
Stamens - anthers smaller than fertile sib, no stomium or filament elongation (8).
Pollen - no staining with 2,3,5-triphenyltetrazolium, but staining with acetocarmine, some normal-appearing grains (8).
No images

Origin of mutant:

A spontaneous mutant in Compana (PI 539111) (5).

Mutational events:

msg18.cq (MSS067, GSHO 1818) in Compana (PI 539111) (5, 6); msg18.z (MSS093) in Betzes (PI 129430) (4, 6); msg18.am (MSS304) in Betzes (3, 6).

Mutant used for description and seed stocks:

msg18.cq (GSHO 1818) in Compana; msg18.cq in Bowman (PI 483237)*7 (GSHO 2117, BW552. NGB24130).
