BGS 373, Male sterile genetic 18, msg18

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

Previous nomenclature and gene symbolization:

Male sterile 18 = ms18 (5).


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).


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).
