BGS 504, Male sterile genetic 41, msg41

BGN  45:191
Stock number: BGS 504
Locus name: Male sterile genetic 41
Locus symbol: msg41

Previous nomenclature and gene symbolization:

Male sterile aj = msg,,aj (6).
Male sterile = 65msx166 (7).


Monofactorial recessive (7).
Located in chromo some 6HS (1); msg41.aj is associated with SNP markers 1_0061 to 1_1250 (positions 70.15 to 82.43 cM) in 6H bins 05 to 06 in a heterozygous plant from Bowman backcross-derived line BW976 (1); the plant of the Bowman backcross-derived line for the stock, BW578, evaluated for SNP markers did not have any deviant markers from those of Bowman (1).


Selfing - none (4, 6).
Outcrossing - complete female fertility (6).
Stamens - anthers rudimentary, no stomium or filament elongation (4, 6).
