BGS 464, Male sterile genetic 27, msg27

BGN  45:174
Stock number: BGS 464
Locus name: Male sterile genetic 27
Locus symbol: msg27

Previous nomenclature and gene symbolization:

Male sterile ae = msg,,ae (7).


Monofactorial recessive (4, 8).
Located in chromosome 2HS (1, 2, 3); did not recombine with the vrs1 (six-rowed spike 1) locus (2); is about 20.5 cM distal from the vrs1 locus (3); is associated with SNP markers 2_1366 to 2_1153 (positions 50.56 to 89.09 cM) in 2H bins 05 to 06 in a heterozygous plant from Bowman backcross-derived line BW562 (1); likely in 2H bin 05.


Selfing - none (5, 7, 8).
Outcrossing - complete female fertility (8).
Stamens - anthers rudimentary, no stomium or filament elongation (5, 8).
