BGS 364, Male sterile genetic 8, msg8
Stock number: BGS 364
Locus name: Male sterile genetic 8
Locus symbol: msg8
Previous nomenclature and gene symbolization:
Male sterile 8 = ms8 (5).
Inheritance:
Monofactorial recessive (5).
Located in chromosome 5HL (3, 6). msg8.ch is about 8.3 cM from the raw1 (smooth awn 1) locus (3); msg8.ch is associated with adjacent SNP markers 2_0127 and 1_1507 (positions 111.21 and 111.56 cM) in 5H bin 10 in a homozygous male sterile plant from Bowman backcross-derived line BW591 (2).
Description:
Selfing - none (5).
Outcrossing - complete female fertility (5).
Stamens - anthers smaller than fertile sibs (5), stomium present, and filament elongation (1, 8).
Pollen - reduced staining (6.9% stains with 2,3,5-triphenyltetrazolium, 20.7% stains with acetocarmine), some grains appear normal (8, 9).
Cytology - normal development and differentiation of microspores up to the free microspore stage (9). Grains are undeveloped, have a stainable ring at the apertural annulus without any actual pore; the exine staining with Fast Blue B is darker than in normal grains (1).
