BGS 469, Male sterile genetic 32, msg32
Stock number: BGS 469
Locus name: Male sterile genetic 32
Locus symbol: msg32
Previous nomenclature and gene symbolization:
Male sterile w = msg,,w (4).
Male sterile = 63msx7 (5).
Inheritance:
Monofactorial recessive (4).
Located in chromosome 7H (2, 4); msg32.w is linked to the nud1 (naked caryopsis 1) locus (2); msg32.w is associated with SNP markers 1_0327 to 2_0911 (positions 55.54 to 107.44 cM) in 7H bins 05 to 07 in a homozygous male sterile plant from Bowman backcross-derived line BW568 (1).
Description:
Selfing - none (4).
Outcrossing - complete female fertility (4).
Stamens - anthers smaller than fertile sibs, no stomium or filament elongation (4).
