BGS 470, Male sterile genetic 33, msg33
Stock number: BGS 470
Locus name: Male sterile genetic 33
Locus symbol: msg33
Previous nomenclature and gene symbolization:
Male sterile x = msg,,x (6).
Male sterile = 63msx8 (7).
Inheritance:
Monofactorial recessive (6).
Located in chromosome 2HS (2); msg33.x is about 5.2 cM distal from the centromere, and 25.6 cM proximal from the vrs1 (six-rowed spike 1) locus (3); msg33.x is associated with SNP markers 2_0458 to 1_1250 (positions 96.47 to 161.08 cM) in 2H bins 07 to 11 in a heterozygous plant from Bowman backcross-derived line BW569 (1).
Description:
Selfing - 20% at Bozeman, Montana, 17% at Tucson, Arizona, USA, and 0% at Elimäki, Finland (5).
Outcrossing - complete female fertility (6).
Stamens - anthers smaller than fertile sibs, stomium present, and filament elongation (6).
